Steps for building and saving the test database

  • Perform the following steps to build and save the test database:

    1. Run the following command from the client system to build the database:

    <CASSANDRA_HOME_DIR>/tools/bin/cassandra-stress user profile=<CASSANDRA_HOME_DIR>/tools/cqlstress-insanity-example.yaml ops\(insert=1\) no-warmup cl=THREE n=total_number_entries -mode native cql3 –pop seq=1..total_number_entries -node <node_IP_address> -rate threads=<number_of_client_threads>

    1. To accelerate compaction and not limit it, modify the default Cassandra throughput temporarily using the following command:

    <CASSANDRA_HOME_DIR>/bin/nodetool setcompactionthroughput 0

    1. After the initial table has been created, wait for all compaction processes to complete before stopping Apache Cassandra:
      1. Flush Cassandra memory buffers using the following command:

    <CASSANDRA_HOME_DIR>/bin/nodetool flush

    1. Wait until all compaction jobs are done using the following command:

    <CASSANDRA_HOME_DIR>/bin/nodetool compactionstats

    1. When the compaction is completed, you can restore the compaction throughput to default:

    <CASSANDRA_HOME_DIR>/bin/nodetool setcompactionthroughput 16
