[checkstyle] consolidate checkstyle plugin configs. default to enforcing.
Sean Busbey authored 
- define checkstyle configs in as few places as possible
- use checkstyle:check since it has defaults that match what we want (fail after logging to console)
- modules that have current failures set property checkstyle.failOnViolation to false.

Kudu bindings for YCSB

Kudu 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
