 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.
