+-->
+
+## Quick Start
+
+This section describes how to run YCSB on [Accumulo](https://accumulo.apache.org/).
+
+### 1. Start Accumulo
+
+See the [Accumulo Documentation](https://accumulo.apache.org/1.7/accumulo_user_manual.html#_installation)
+for details on installing and running Accumulo.
+
+Before running the YCSB test you must create the Accumulo table. Again see the
+[Accumulo Documentation](https://accumulo.apache.org/1.7/accumulo_user_manual.html#_basic_administration)
+for details. The default table name is `ycsb`.
+
+### 2. Set Up YCSB
+
+Git clone YCSB and compile:
+
+ git clone http://github.com/brianfrankcooper/YCSB.git
+ cd YCSB
+ mvn -pl com.yahoo.ycsb:aerospike-binding -am clean package
+
+### 3. Load Data and Run Tests
+
+Load the data:
+
+ ./bin/ycsb load accumulo -s -P workloads/workloada \
+ -p accumulo.zooKeepers=localhost \
+ -p accumulo.columnFamily=ycsb \
+ -p accumulo.instanceName=ycsb \
+ -p accumulo.username=user \
+ -p accumulo.password=supersecret \
+ > outputLoad.txt
+
+Run the workload test:
+
+ ./bin/ycsb run accumulo -s -P workloads/workloada \
+ -p accumulo.zooKeepers=localhost \
+ -p accumulo.columnFamily=ycsb \
+ -p accumulo.instanceName=ycsb \
+ -p accumulo.username=user \
+ -p accumulo.password=supersecret \
+ > outputLoad.txt
+
+## Accumulo Configuration Parameters
+
+- `accumulo.zooKeepers`
+ - The Accumulo cluster's [zookeeper servers](https://accumulo.apache.org/1.7/accumulo_user_manual.html#_connecting).
+ - Should contain a comma separated list of of hostname or hostname:port values.
+ - No default value.
+
+- `accumulo.columnFamily`
+ - The name of the column family to use to store the data within the table.
+ - No default value.
+
+- `accumulo.instanceName`
+ - Name of the Accumulo [instance](https://accumulo.apache.org/1.7/accumulo_user_manual.html#_connecting).
+ - No default value.
+
+- `accumulo.username`
+ - The username to use when connecting to Accumulo.
+ - No default value.
+
+- `accumulo.password`
+ - The password for the user connecting to Accumulo.
+ - No default value.

+# THIS BINDING IS DEPRECATED
+----------------------------
+Date of removal from YCSB: **March 2016**
+
+Due to the low amount of use and support for older Cassandra lineages (0.X and 1.X), YCSB will not support clients for these versions either.
+
+For Cassandra 2.X use the ```cassandra2-cql``` client: https://github.com/brianfrankcooper/YCSB/tree/master/cassandra2.
+
+# Cassandra (0.7, 0.8, 1.x) drivers for YCSB
+
+**For Cassandra 2 CQL support, use the `cassandra2-cql` binding. The Thrift drivers below are deprecated, and the CQL driver here does not support Cassandra 2.1+.**
+
+There are three drivers in the Cassandra binding:
+
+* `cassandra-7`: Cassandra 0.7 Thrift binding.
+* `cassandra-8`: Cassandra 0.8 Thrift binding.
+* `cassandra-10`: Cassandra 1.0+ Thrift binding.
+* `cassandra-cql`: Cassandra CQL binding, for Cassandra 1.x to 2.0. See `cassandra2/README.md` for details on parameters.
+
+# `cassandra-10`
+
+## Creating a table
+
+Using `cassandra-cli`:
+
+ create keyspace usertable with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy' and strategy_options = {replication_factor:1};
+
+ create column family data with column_type = 'Standard' and comparator = 'UTF8Type';
+
+**Note that `replication_factor` and consistency levels (below) will affect performance.**
+
+## Configuration Parameters
+
+- `hosts` (**required**)
+ - Cassandra nodes to connect to.
+ - No default.
+
+* `port`
+ - Thrift port for communicating with Cassandra cluster.
+ * Default is `9160`.
+
+- `cassandra.columnfamily`
+ - Column family name - must match the column family for the table created (see above).
+ - Default value is `data`
+
+- `cassandra.username`
+- `cassandra.password`
+ - Optional user name and password for authentication. See http://docs.datastax.com/en/cassandra/2.0/cassandra/security/security_config_native_authenticate_t.html for details.
+
+* `cassandra.readconsistencylevel`
+* `cassandra.scanconsistencylevel`
+* `cassandra.writeconsistencylevel`
+
+ - Default value is `ONE`
+ - Consistency level for reads and writes, respectively. See the [DataStax documentation](http://docs.datastax.com/en/cassandra/2.0/cassandra/dml/dml_config_consistency_c.html) for details.
+ - *Note that the default setting does not provide durability in the face of node failure. Changing this setting will affect observed performance.* See also `replication_factor`, above.

* Tested with Cassandra 2.0, CQL client for YCSB framework
- *
- * In CQLSH, create keyspace and table. Something like:
- * cqlsh> create keyspace ycsb
- * WITH REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor': 1 };
- * cqlsh> create table usertable (
- * y_id varchar primary key,
- * field0 varchar,
- * field1 varchar,
- * field2 varchar,
- * field3 varchar,
- * field4 varchar,
- * field5 varchar,
- * field6 varchar,
- * field7 varchar,
- * field8 varchar,
- * field9 varchar);
+ *
+ * See {@code cassandra2} for a version compatible with Cassandra 2.1+. See

+# Apache Cassandra 2.x CQL binding
+
+Binding for [Apache Cassandra](http://cassandra.apache.org), using the CQL API
+via the [DataStax
+driver](http://docs.datastax.com/en/developer/java-driver/2.1/java-driver/whatsNew2.html).
+
+To run against the (deprecated) Cassandra Thrift API, use the `cassandra-10` binding.
+
+## Creating a table for use with YCSB
+
+For keyspace `ycsb`, table `usertable`:
+
+ cqlsh> create keyspace ycsb
+ WITH REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor': 3 };
+ cqlsh> USE ycsb;
+ cqlsh> create table usertable (
+ y_id varchar primary key,
+ field0 varchar,
+ field1 varchar,
+ field2 varchar,
+ field3 varchar,
+ field4 varchar,
+ field5 varchar,
+ field6 varchar,
+ field7 varchar,
+ field8 varchar,
+ field9 varchar);
+
+**Note that `replication_factor` and consistency levels (below) will affect performance.**
+
+## Cassandra Configuration Parameters
+
+- `hosts` (**required**)
+ - Cassandra nodes to connect to.
+ - No default.
+
+* `port`
+ * CQL port for communicating with Cassandra cluster.
+ * Default is `9042`.

+## Scans in the CouchbaseClient
+The scan operation in the CouchbaseClient requires a Couchbase View to be created manually. To do this:
+1. Go to the Couchbase UI, then to Views
+2. Create a new development view, specify a ddoc and view name, use these in your YCSB properties. See Configuration Options below.
+3. The default map code is sufficient.
+4. Save, and publish this View.
+
## Configuration Options
Since no setup is the same and the goal of YCSB is to deliver realistic benchmarks, here are some setups that you can tune. Note that if you need more flexibility (let's say a custom transcoder), you still need to extend this driver and implement the facilities on your own.

-<P>
-A layer for accessing a database to be benchmarked. Each thread in the client
- will be given its own instance of whatever DB class is to be used in the test.
- This class should be constructed using a no-argument constructor, so we can
- load it dynamically. Any argument-based initialization should be
- done by init().
-
- Note that YCSB does not make any use of the return codes returned by this class.
- Instead, it keeps a count of the return values and presents them to the user.
-
- The semantics of methods such as insert, update and delete vary from database
- to database. In particular, operations may or may not be durable once these
- methods commit, and some systems may return 'success' regardless of whether
- or not a tuple with a matching key existed before the call. Rather than dictate
- the exact semantics of these methods, we recommend you either implement them
- to match the database's default semantics, or the semantics of your
- target application. For the sake of comparison between experiments we also
- recommend you explain the semantics you chose when presenting performance results.

-A generator of a zipfian distribution. It produces a sequence of items, such that some items are more popular than others, according
- to a zipfian distribution. When you construct an instance of this class, you specify the number of items in the set to draw from, either
- by specifying an itemcount (so that the sequence is of items from 0 to itemcount-1) or by specifying a min and a max (so that the sequence is of
- items from min to max inclusive). After you construct the instance, you can change the number of items by calling nextInt(itemcount) or nextLong(itemcount).
-
- Unlike @ZipfianGenerator, this class scatters the "popular" items across the itemspace. Use this, instead of @ZipfianGenerator, if you
- don't want the head of the distribution (the popular items) clustered together.

-One experiment scenario. One object of this type will
- be instantiated and shared among all client threads. This class
- should be constructed using a no-argument constructor, so we can
- load it dynamically. Any argument-based initialization should be
- done by init().
-
- If you extend this class, you should support the "insertstart" property. This
- allows the load phase to proceed from multiple clients on different machines, in case
- the client is the bottleneck. For example, if we want to load 1 million records from
- 2 machines, the first machine should have insertstart=0 and the second insertstart=500000. Additionally,
- the "insertcount" property, which is interpreted by Client, can be used to tell each instance of the
- client how many inserts to do. In the example above, both clients should have insertcount=500000.

-A generator of a zipfian distribution. It produces a sequence of items, such that some items are more popular than others, according
- to a zipfian distribution. When you construct an instance of this class, you specify the number of items in the set to draw from, either
- by specifying an itemcount (so that the sequence is of items from 0 to itemcount-1) or by specifying a min and a max (so that the sequence is of
- items from min to max inclusive). After you construct the instance, you can change the number of items by calling nextInt(itemcount) or nextLong(itemcount).
-
- Note that the popular items will be clustered together, e.g. item 0 is the most popular, item 1 the second most popular, and so on (or min is the most
- popular, min+1 the next most popular, etc.) If you don't want this clustering, and instead want the popular items scattered throughout the
- item space, then use ScrambledZipfianGenerator instead.
-
- Be aware: initializing this generator may take a long time if there are lots of items to choose from (e.g. over a minute
- for 100 million objects). This is because certain mathematical values need to be computed to properly generate a zipfian skew, and one of those
- values (zeta) is a sum sequence from 1 to n, where n is the itemcount. Note that if you increase the number of items in the set, we can compute
- a new zeta incrementally, so it should be fast unless you have added millions of items. However, if you decrease the number of items, we recompute
- zeta from scratch, so this can take a long time.

-How This API Document Is Organized</H1>
-</CENTER>
-This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.<H3>
-Overview</H3>
-<BLOCKQUOTE>
-
-<P>
-The <A HREF="overview-summary.html">Overview</A> page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall description of the set of packages.</BLOCKQUOTE>
-<H3>
-Package</H3>
-<BLOCKQUOTE>
-
-<P>
-Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:<UL>
-<LI>Interfaces (italic)<LI>Classes<LI>Enums<LI>Exceptions<LI>Errors<LI>Annotation Types</UL>
-</BLOCKQUOTE>
-<H3>
-Class/Interface</H3>
-<BLOCKQUOTE>
-
-<P>
-Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:<UL>
-<LI>Class inheritance diagram<LI>Direct Subclasses<LI>All Known Subinterfaces<LI>All Known Implementing Classes<LI>Class/interface declaration<LI>Class/interface description
-<P>
-<LI>Nested Class Summary<LI>Field Summary<LI>Constructor Summary<LI>Method Summary
-<P>
-<LI>Field Detail<LI>Constructor Detail<LI>Method Detail</UL>
-Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.</BLOCKQUOTE>
-</BLOCKQUOTE>
-<H3>
-Annotation Type</H3>
-<BLOCKQUOTE>
-
-<P>
-Each annotation type has its own separate page with the following sections:<UL>
-<LI>Annotation Type declaration<LI>Annotation Type description<LI>Required Element Summary<LI>Optional Element Summary<LI>Element Detail</UL>
-</BLOCKQUOTE>
-</BLOCKQUOTE>
-<H3>
-Enum</H3>
-<BLOCKQUOTE>
-
-<P>
-Each enum has its own separate page with the following sections:<UL>
-<LI>Enum declaration<LI>Enum description<LI>Enum Constant Summary<LI>Enum Constant Detail</UL>
-</BLOCKQUOTE>
-<H3>
-Tree (Class Hierarchy)</H3>
-<BLOCKQUOTE>
-There is a <A HREF="overview-tree.html">Class Hierarchy</A> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with <code>java.lang.Object</code>. The interfaces do not inherit from <code>java.lang.Object</code>.<UL>
-<LI>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.<LI>When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.</UL>
-</BLOCKQUOTE>
-<H3>
-Deprecated API</H3>
-<BLOCKQUOTE>
-The <A HREF="deprecated-list.html">Deprecated API</A> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</BLOCKQUOTE>
-<H3>
-Index</H3>
-<BLOCKQUOTE>
-The <A HREF="index-all.html">Index</A> contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.</BLOCKQUOTE>
-<H3>
-Prev/Next</H3>
-These links take you to the next or previous class, interface, package, or related page.<H3>
-Frames/No Frames</H3>
-These links show and hide the HTML frames. All pages are available with or without frames.
-<P>
-<H3>
-Serialized Form</H3>
-Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.
-<P>
-<H3>
-Constant Field Values</H3>
-The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.
-<P>
-<FONT SIZE="-1">
-<EM>
-This help file applies to API documentation generated using the standard doclet.</EM>

+# keys from YCSB are hashed across multiple hash partitions and
+# performance of individual operations are good. However, query across
+# multiple items is eventually consistent in this mode and relies on the
+# global secondary index.
+#
+#
+# When testing the DB in HASH_AND_RANGE mode, your table's primary key must be
+# of the "HASH_AND_RANGE" key type. You need to specify the name of the
+# hash key via the "dynamodb.hashKeyName" property and you also need to
+# specify the name of the range key via the "dynamodb.primaryKey" property.
+# In this mode, keys supplied by YCSB will be used as the range part of
+# the primary key and the hash part of the primary key will have a fixed value.
+# Optionally you can designate the value used in the hash part of the primary
+# key via the dynamodb.hashKeyValue.
+#
+# The purpose of the HASH_AND_RANGE mode is to benchmark the performance
+# characteristics of a single logical hash partition. This is useful because
+# so far the only practical way to do strongly consistent query is to do it
+# in a single hash partition (Whole table scan can be consistent but it becomes
+# less practical when the table is really large). Therefore, for users who
+# really want to have strongly consistent query, it's important for them to
+# know the performance capabilities of a single logical hash partition so
+# they can plan their application accordingly.
+
+#dynamodb.primaryKeyType = HASH
+
+#Optionally you can specify a value for the hash part of the primary key
+#when testing in HASH_AND_RANG mode.
+#dynamodb.hashKeyValue = <some value of your choice>

# Endpoint to connect to.For best latency, it is recommended
# to choose the endpoint which is closer to the client.
# Default is us-east-1

+## Configure
+
+ YCSB_HOME - YCSB home directory
+ DATASTORE_HOME - Google Cloud Datastore YCSB client package files
+
+Please refer to https://github.com/brianfrankcooper/YCSB/wiki/Using-the-Database-Libraries
+for more information on setup.
+
+# Benchmark
+
+ $YCSB_HOME/bin/ycsb load googledatastore -P workloads/workloada -P googledatastore.properties
+ $YCSB_HOME/bin/ycsb run googledatastore -P workloads/workloada -P googledatastore.properties
+
+# Properties
+
+ $DATASTORE_HOME/conf/googledatastore.properties
+
+# Details
+
+A. Configuration and setup:
+
+See this link for instructions about setting up Google Cloud Datastore and
+authentication:
+
+https://cloud.google.com/datastore/docs/getstarted/start_java/
+
+After you setup your environment, you will have 3 pieces of information ready:
+- datasetId,
+- service account email, and
+- a private key file in P12 format.
+
+These will be configured via corresponding properties in the googledatastore.properties file.
+
+B. EntityGroupingMode
+
+In Google Datastore, Entity Group is the unit in which the user can
+perform strongly consistent query on multiple items; Meanwhile, Entity group
+also has certain limitations in performance, especially with write QPS.
+
+We support two modes here:
+
+1. [default] One entity per group (ONE_ENTITY_PER_GROUP)
+
+In this mode, every entity is a "root" entity and sits in one group,
+and every entity group has only one entity. Write QPS is high in this
+mode (and there is no documented limitation on this). But query across
+multiple entities are eventually consistent.
+
+When this mode is set, every entity is created with no ancestor key (meaning
+the entity itself is the "root" entity).
+
+2. Multiple entities per group (MULTI_ENTITY_PER_GROUP)
+
+In this mode, all entities in one benchmark run are placed under one
+ancestor (root) node therefore inside one entity group. Query/scan
+performed on these entities will be strongly consistent but write QPS
+will be subject to documented limitation (current is at 1 QPS).
+
+Because of the write QPS limit, it's highly recommended that you rate
+limit your benchmark's test rate to avoid excessive errors.
+
+The goal of this MULTI_ENTITY_PER_GROUP mode is to allow user to
+benchmark and understand performance characteristics of a single entity
+group of the Google Datastore.
+
+While in this mode, one can optionally specify a root key name. If not
+specified, a default name will be used.

+# Run YCSB
Make sure that an instance of Hypertable is running. To access the database
through the YCSB shell, from the YCSB directory run:
-]$ ./bin/ycsb shell hypertable -p columnfamily=family
+ ]$ ./bin/ycsb shell hypertable -p columnfamily=family
where the value passed to columnfamily matches that used in the table
creation. To run a workload, first load the data:
-]$ ./bin/ycsb load hypertable -P workloads/workloada -p columnfamily=family
+ ]$ ./bin/ycsb load hypertable -P workloads/workloada -p columnfamily=family
Then run the workload:
-]$ ./bin/ycsb run hypertable -P workloads/workloada -p columnfamily=family

This example runs the core workload 'workloada' that comes packaged with YCSB.
The state of the YCSB data in the Hypertable database can be reset by dropping
usertable and recreating it.

+
+# JDBC Driver for YCSB
+This driver enables YCSB to work with databases accessible via the JDBC protocol.
+
+## Getting Started
+### 1. Start your database
+This driver will connect to databases that use the JDBC protocol, please refer to your databases documentation on information on how to install, configure and start your system.
+
+### 2. Set up YCSB
+You can clone the YCSB project and compile it to stay up to date with the latest changes. Or you can just download the latest release and unpack it. Either way, instructions for doing so can be found here: https://github.com/brianfrankcooper/YCSB.
+
+### 3. Configure your database and table.
+You can name your database what ever you want, you will need to provide the database name in the JDBC connection string.
+
+You can name your table whatever you like also, but it needs to be specified using the YCSB core properties, the default is to just use 'usertable' as the table name.
+
+The expected table schema will look similar to the following, syntactical differences may exist with your specific database:
+
+```sql
+CREATE TABLE usertable (
+ YCSB_KEY VARCHAR(255) PRIMARY KEY,
+ FIELD0 TEXT, FIELD1 TEXT,
+ FIELD2 TEXT, FIELD3 TEXT,
+ FIELD4 TEXT, FIELD5 TEXT,
+ FIELD6 TEXT, FIELD7 TEXT,
+ FIELD8 TEXT, FIELD9 TEXT
+);
+```
+
+Key take aways:
+
+* The primary key field needs to be named YCSB_KEY
+* The other fields need to be prefixed with FIELD and count up starting from 1
+* Add the same number of FIELDs as you specify in the YCSB core properties, default is 10.
+* The type of the fields is not so important as long as they can accept strings of the length that you specify in the YCSB core properties, default is 100.
+
+#### JdbcDBCreateTable Utility
+YCSB has a utility to help create your SQL table. NOTE: It does not support all databases flavors, if it does not work for you, you will have to create your table manually with the schema given above. An example usage of the utility:
+
+```sh
+java -cp YCSB_HOME/jdbc-binding/lib/jdbc-binding-0.4.0.jar:mysql-connector-java-5.1.37-bin.jar com.yahoo.ycsb.db.JdbcDBCreateTable -P testworkload -P db.properties -n usertable
+```
+
+Hint: you need to include your Driver jar in the classpath as well as specify your loading options via a workload file, JDBC connection information, and a table name with ```-n```.
+
+Simply executing the JdbcDBCreateTable class without any other parameters will print out usage information.
+
+### 4. Configure YCSB connection properties
+You need to set the following connection configurations:
+
+```sh
+db.driver=com.mysql.jdbc.Driver
+db.url=jdbc:mysql://127.0.0.1:3306/ycsb
+db.user=admin
+db.passwd=admin
+```
+
+Be sure to use your driver class, a valid JDBC connection string, and credentials to your database.
+
+You can add these to your workload configuration or a separate properties file and specify it with ```-P``` or you can add the properties individually to your ycsb command with ```-p```.
+
+### 5. Add your JDBC Driver to the classpath
+There are several ways to do this, but a couple easy methods are to put a copy of your Driver jar in ```YCSB_HOME/jdbc-binding/lib/``` or just specify the path to your Driver jar with ```-cp``` in your ycsb command.
+
+### 6. Running a workload
+Before you can actually run the workload, you need to "load" the data first.
+
+```sh
+bin/ycsb load jdbc -P workloads/workloada -P db.properties -cp mysql-connector-java.jar
+```
+
+Then, you can run the workload:
+
+```sh
+bin/ycsb run jdbc -P workloads/workloada -P db.properties -cp mysql-connector-java.jar
+```
+
+## Configuration Properties
+
+```sh
+db.driver=com.mysql.jdbc.Driver # The JDBC driver class to use.
+db.url=jdbc:mysql://127.0.0.1:3306/ycsb # The Database connection URL.
+db.user=admin # User name for the connection.
+db.passwd=admin # Password for the connection.
+jdbc.fetchsize=10 # The JDBC fetch size hinted to the driver.
+jdbc.autocommit=true # The JDBC connection auto-commit property for the driver.
+```
+
+Please refer to https://github.com/brianfrankcooper/YCSB/wiki/Core-Properties for all other YCSB core properties.

+# Kudu bindings for YCSB
+
+[Kudu](http://getkudu.io) is a storage engine that enables fast analytics on fast data.
+
+## Benchmarking Kudu
+
+Use the following command line to load the initial data into an existing Kudu cluster with default
+configurations.
+
+```
+bin/ycsb load kudu -P workloads/workloada
+```
+
+Additional configurations:
+* `kudu_master_addresses`: The master's address. The default configuration expects a master on localhost.
+* `kudu_pre_split_num_tablets`: The number of tablets (or partitions) to create for the table. The default
+uses 4 tablets. A good rule of thumb is to use 5 per tablet server.
+* `kudu_table_num_replicas`: The number of replicas that each tablet will have. The default is 3. Should
+only be configured to use 1 instead, for single node tests.
+* `kudu_sync_ops`: If the client should wait after every write operation. The default is true.
+* `kudu_block_size`: The data block size used to configure columns. The default is 4096 bytes.
+
+Then, you can run the workload:
+
+```
+bin/ycsb run kudu -P workloads/workloada
+```

+# YCSB Memcached binding
+
+This section describes how to run YCSB on memcached.
+
+## 1. Install and start memcached service on the host(s)
+
+Debian / Ubuntu:
+
+ sudo apt-get install memcached
+
+RedHat / CentOS:
+
+ sudo yum install memcached
+
+## 2. Install Java and Maven
+
+See step 2 in [`../mongodb/README.md`](../mongodb/README.md).
+
+## 3. Set up YCSB
+
+Git clone YCSB and compile:
+
+ git clone http://github.com/brianfrankcooper/YCSB.git
+ cd YCSB
+ mvn -pl com.yahoo.ycsb:memcached-binding -am clean package
+
+## 4. Load data and run tests
+
+Load the data:
+
+ ./bin/ycsb load memcached -s -P workloads/workloada > outputLoad.txt
+
+Run the workload test:
+
+ ./bin/ycsb run memcached -s -P workloads/workloada > outputRun.txt
+
+## 5. memcached Connection Parameters
+
+A sample configuration is provided in
+[`conf/memcached.properties`](conf/memcached.properties).
+
+### Required params
+
+- `memcached.hosts`
+
+ This is a comma-separated list of hosts providing the memcached interface.
+ You can use IPs or hostnames. The port is optional and defaults to the
+ memcached standard port of `11211` if not specified.
+
+### Optional params
+
+- `memcached.shutdownTimeoutMillis`
+
+ Shutdown timeout in milliseconds.
+
+- `memcached.objectExpirationTime`
+
+ Object expiration time for memcached; defaults to `Integer.MAX_VALUE`.
+
+- `memcached.checkOperationStatus`
+
+ Whether to verify the success of each operation; defaults to true.
+
+- `memcached.readBufferSize`
+
+ Read buffer size, in bytes.
+
+- `memcached.opTimeoutMillis`
+
+ Operation timeout, in milliseconds.
+
+- `memcached.failureMode`
+
+ What to do with failures; this is one of `net.spy.memcached.FailureMode` enum
+ values, which are currently: `Redistribute`, `Retry`, or `Cancel`.
+
+You can set properties on the command line via `-p`, e.g.:
+
+ ./bin/ycsb load memcached -s -P workloads/workloada \
+ -p "memcached.hosts=127.0.0.1" > outputLoad.txt

@@ -39,10 +39,38 @@ Then, run the workload:
See the next section for the list of configuration parameters for OrientDB.
-## OrientDB Configuration Parameters
+## DB creation with the OrientDBClient
+This client will create a database for you if the connection database you specify does not exists. You can also specify connection information to a preexisting database.
+
+You can use the ```orientdb.newdb=true``` property to allow this client to drop and create a new database instance during the ```load``` phase.
-### `OrientDB.url` (default: `local:C:/temp/databases/ycsb`)
+NOTE: understand that using the ```orientdb.newdb=true``` property will drop and recreate databases even if it was a preexisting instance.
-### `OrientDB.user` (default `admin`)
+WARNING: Creating a new database will be done safely with multiple threads on a single YCSB instance, but is not guaranteed to work when launching multiple YCSB instances. In that scenario it is suggested that you create the db before hand, or run the ```load``` phase with a single YCSB instance.
+
+## OrientDB Configuration Parameters
-### `OrientDB.password` (default `admin`)
+* ```orientdb.url``` - (required) The address to your database.
+ * Supported storage types: memory, plocal, remote
+ * EX. ```plocal:/path/to/database```
+* ```orientdb.user``` - The user to connect to the database with.
+ * Default: ```admin```
+* ```orientdb.password``` - The password to connect to the database with.
+ * Default: ```admin```
+* ```orientdb.newdb``` - Overwrite the database if it already exists.
+ * Only effects the ```load``` phase.
+ * Default: ```false```
+* ```orientdb.intent``` - Declare an Intent to the database.
+ * This is an optimization feature provided by OrientDB: http://orientdb.com/docs/2.1/Performance-Tuning.html#massive-insertion
+ * Possible values are:
+ * massiveinsert
+ * massiveread
+ * nocache
+* ```orientdb.remote.storagetype``` - Storage type of the database on remote server
+ * This is only required if using a ```remote:``` connection url
+
+## Known Issues
+
+* There is a performance issue around the scan operation. This binding uses OIndex.iterateEntriesMajor() which will return unnecessarily large iterators. This has a performance impact as the recordcount goes up. There are ideas in the works to fix it, track it here: [#568](https://github.com/brianfrankcooper/YCSB/issues/568).
+* The OIndexCursor used to run the scan operation currently seems to be broken. Because of this, if the startkey and recordcount combination on a particular operation were to cause the iterator to go to the end, a NullPointerException is thrown. With sufficiently high record counts, this does not happen very often, but it could cause false negatives. Track that issue here: https://github.com/orientechnologies/orientdb/issues/5541.
+* Iterator methods needed to perform scans are Unsupported in the OrientDB API for remote database connections and so will return NOT_IMPLEMENTED status if attempted.

+LICENSE file.
+-->
+Quick Start
+===============
+### 1. Set Up YCSB
+
+Download the YCSB from this website:
+
+ https://github.com/brianfrankcooper/YCSB/releases/
+
+You can choose to download either the full stable version or just one of the available binding.
+
+### 2. Configuration of the AWS credentials
+
+The access key ID and secret access key as well as the endPoint and region and the Client configurations like the maxErrorRetry can be set in a properties file under s3-binding/conf/s3.properties or sent by command line (see below).
+It is highly suggested to use the property file instead of to send the credentials through the command line.
+
+
+### 3. Run YCSB
+
+To execute the benchmark using the S3 storage binding, first files must be uploaded using the "load" option with this command:
+
+ ./bin/ycsb load s3 -p table=theBucket -p s3.endPoint=s3.amazonaws.com -p s3.accessKeyId=yourAccessKeyId -p s3.secretKey=yourSecretKey -p fieldlength=10 -p fieldcount=20 -P workloads/workloada
+
+With this command, the workload A will be executing with the loading phase. The file size is determined by the number of fields (fieldcount) and by the field size (fieldlength). In this case each file is 200 bytes (10 bytes for each field multiplied by 20 fields).
+
+Running the command:
+
+ ./bin/ycsb -t s3 -p table=theBucket -p s3.endPoint=s3.amazonaws.com -p s3.accessKeyId=yourAccessKeyId -p s3.secretKey=yourSecretKey -p fieldlength=10 -p fieldcount=20 -P workloads/workloada
+
+the workload A will be executed with file size 200 bytes.
+
+#### S3 Storage Configuration Parameters
+
+The parameters to configure the S3 client can be set using the file "s3-binding/conf/s3.properties". This is highly advisable for the parameters s3.accessKeyId and s3.secretKey. All the other parameters can be set also on the command line. Here the list of all the parameters that is possible to configure:
+
+- `table`
+ - This should be a S3 Storage bucket name and it replace the standard table name assigned by YCSB.
+
+- `s3.endpoint`
+ - This indicate the endpoint used to connect to the S3 Storage service.
+ - Default value is `s3.amazonaws.com`.
+
+- `s3.region`
+ - This indicate the region where your buckets are.
+ - Default value is `us-east-1`.
+
+- `s3.accessKeyId`
+ - This is the accessKey of your S3 account.
+
+- `s3.secretKey`
+ - This is the secret associated with your S3 account.
+
+- `s3.maxErrorRetry`
+ - This is the maxErrorRetry parameter for the S3Client.
+
+- `s3.protocol`
+ - This is the protocol parameter for the S3Client. The default value is HTTPS.
+
+- `s3.sse`
+ - This parameter set to true activates the Server Side Encryption.
+
+- `s3.ssec`
+ - This parameter if not null activates the SSE-C client side encryption. The value passed with this parameter is the client key used to encrpyt the files.

+
+## Quick Start
+
+This section describes how to run YCSB on Solr running locally.
+
+### 1. Set Up YCSB
+
+Clone the YCSB git repository and compile:
+
+ git clone git://github.com/brianfrankcooper/YCSB.git
+ cd YCSB
+ mvn -pl com.yahoo.ycsb:solr-binding -am clean package
+
+### 2. Set Up Solr
+
+There must be a running Solr instance with a core/collection pre-defined and configured.
+- See this [API](https://cwiki.apache.org/confluence/display/solr/CoreAdmin+API#CoreAdminAPI-CREATE) reference on how to create a core.
+- See this [API](https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-api1) reference on how to create a collection in SolrCloud mode.
+
+The `conf/schema.xml` configuration file present in the core/collection just created must be configured to handle the expected field names during benchmarking.
+Below illustrates a sample from a schema config file that matches the default field names used by the ycsb client:
+
+ <field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false"/>
+ <field name="field0" type="text_general" indexed="true" stored="true"/>
+ <field name="field1" type="text_general" indexed="true" stored="true"/>
+ <field name="field2" type="text_general" indexed="true" stored="true"/>
+ <field name="field3" type="text_general" indexed="true" stored="true"/>
+ <field name="field4" type="text_general" indexed="true" stored="true"/>
+ <field name="field5" type="text_general" indexed="true" stored="true"/>
+ <field name="field6" type="text_general" indexed="true" stored="true"/>
+ <field name="field7" type="text_general" indexed="true" stored="true"/>
+ <field name="field8" type="text_general" indexed="true" stored="true"/>
+ <field name="field9" type="text_general" indexed="true" stored="true"/>
+
+If running in SolrCloud mode ensure there is an external Zookeeper cluster running.
+- See [here](https://cwiki.apache.org/confluence/display/solr/Setting+Up+an+External+ZooKeeper+Ensemble) for details on how to set up an external Zookeeper cluster.
+- See [here](https://cwiki.apache.org/confluence/display/solr/Using+ZooKeeper+to+Manage+Configuration+Files) for instructions on how to use Zookeeper to manage your core/collection configuration files.
+
+### 3. Run YCSB
+
+Now you are ready to run! First, load the data:
+
+ ./bin/ycsb load solr -s -P workloads/workloada -p table=<core/collection name>
+
+Then, run the workload:
+
+ ./bin/ycsb run solr -s -P workloads/workloada -p table=<core/collection name>
+
+For further configuration see below:
+
+### Default Configuration Parameters
+The default settings for the Solr node that is created is as follows:
+
+- `solr.cloud`
+ - A Boolean value indicating if Solr is running in SolrCloud mode. If so there must be an external Zookeeper cluster running also.
+ - Default value is `false` and therefore expects solr to be running in stand-alone mode.
+
+- `solr.base.url`
+ - The base URL in which to interface with a running Solr instance in stand-alone mode
+ - Default value is `http://localhost:8983/solr
+
+- `solr.commit.within.time`
+ - The max time in ms to wait for a commit when in batch mode, ignored otherwise
+ - Default value is `1000ms`
+
+- `solr.batch.mode`
+ - Indicates if inserts/updates/deletes should be commited in batches (frequency controlled by the `solr.commit.within.time` parameter) or commit 1 document at a time.
+ - Default value is `false`
+
+- `solr.zookeeper.hosts`
+ - A list of comma seperated host:port pairs of Zookeeper nodes used to manage SolrCloud configurations.
+ - Must be passed when in [SolrCloud](https://cwiki.apache.org/confluence/display/solr/SolrCloud) mode.
+ - Default value is `localhost:2181`
+
+### Custom Configuration
+If you wish to customize the settings used to create the Solr node
+you can created a new property file that contains your desired Solr
+node settings and pass it in via the parameter to 'bin/ycsb' script. Note that
+the default properties will be kept if you don't explicitly overwrite them.
+
+Assuming that we have a properties file named "myproperties.data" that contains
+custom Solr node configuration you can execute the following to
+pass it into the Solr client:
+
+ ./bin/ycsb run solr -P workloads/workloada -P myproperties.data -s
+
+If you wish to use SolrCloud mode ensure a Solr cluster is running with an
+external zookeeper cluster and an appropriate collection has been created.
+Make sure to pass the following properties as parameters to 'bin/ycsb' script.
+
+ solr.cloud=true
+ solr.zookeeper.hosts=<zkHost2>:<zkPort1>,...,<zkHostN>:<zkPortN>

# How the latency measurements are presented

+# When measurementtype is set to raw, measurements will be output
+# as RAW datapoints in the following csv format:
+# "operation, timestamp of the measurement, latency in us"
+#
+# Raw datapoints are collected in-memory while the test is running. Each
+# data point consumes about 50 bytes (including java object overhead).
+# For a typical run of 1 million to 10 million operations, this should
+# fit into memory most of the time. If you plan to do 100s of millions of
+# operations per run, consider provisioning a machine with larger RAM when using
+# the RAW measurement type, or split the run into multiple runs.
+#
+# Optionally, you can specify an output file to save raw datapoints.
+# Otherwise, raw datapoints will be written to stdout.
+# The output file will be appended to if it already exists, otherwise
+# a new output file will be created.

+# Latency reporting.
+#
+# YCSB records latency of failed operations separately from successful ones.
+# Latency of all OK operations will be reported under their operation name,
+# such as [READ], [UPDATE], etc.
+#
+# For failed operations:
+# By default we don't track latency numbers of specific error status.
+# We just report latency of all failed operation under one measurement name
+# such as [READ-FAILED]. But optionally, user can configure to have either:
+# 1. Record and report latency for each and every error status code by
+# setting reportLatencyForEachError to true, or
+# 2. Record and report latency for a select set of error status codes by
+# providing a CSV list of Status codes via the "latencytrackederrors"
+# property.
+# reportlatencyforeacherror=false
+# latencytrackederrors="<comma separated strings of error codes>"
+
+# Insertion error retry for the core workload.
+#
+# By default, the YCSB core workload does not retry any operations.
+# However, during the load process, if any insertion fails, the entire
+# load process is terminated.
+# If a user desires to have more robust behavior during this phase, they can
+# enable retry for insertion by setting the following property to a positive
+# number.
+# core_workload_insertion_retry_limit = 0
+#
+# the following number controls the interval between retries (in seconds):
+# core_workload_insertion_retry_interval = 3
