+# 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:
+* `masterQuorum`: The master's address. The default configuration expects a master on localhost.
+* `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.
+* `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.
+* `sync_ops`: If the client should buffer data before sending it. The default is false. Should
+always be set to true for the run phase.
+
+Then, you can run the workload:
+
+```
+bin/ycsb run kudu -P workloads/workloada -p sync_ops=true
+```
