Configuring client-to-server compression

Updated on March 11, 2021

This content applies only to On-premises and Client-managed cloud environments

Specify how you want to compress the communication between Pega Platform and Cassandra. By using compression, you reduce the size of the data written to disk, and increase read and write throughput.

Important: The default compression settings ensure the highest performance.
Configure client-to-server compression by editing the corresponding prconfig.xml settings.

For more information about specifying settings through the prconfig.xml file, see Changing node settings by modifying the prconfig.xml file.

  • If you want to use LZ4 compression, set the value of dnode/cassandra_client_compression to LZ4.
    Note: This is the default setting for client-to-server compression.
  • If you want to use Snappy compression, set the value of dnode/cassandra_client_compression to SNAPPY.
  • If you do not want to use client-to-server compression, set the value of dnode/cassandra_client_compression to NONE.
