Quick Start

This section describes how to run YCSB on OrientDB running locally.

1. Set Up YCSB

Clone the YCSB git repository and compile:

git clone https://github.com/brianfrankcooper/YCSB.git
cd YCSB
mvn clean package

2. Run YCSB

Now you are ready to run! First, load the data:

./bin/ycsb load orientdb -s -P workloads/workloada

Then, run the workload:

./bin/ycsb run orientdb -s -P workloads/workloada

See the next section for the list of configuration parameters for OrientDB.

OrientDB Configuration Parameters

OrientDB.url (default: local:C:/temp/databases/ycsb)

OrientDB.user (default admin)

OrientDB.password (default admin)

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.
• 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.
