Configuring node-to-node compression (deprecated)

Updated on July 5, 2022

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

Specify how you want to compress the contents of Cassandra SSTables in the internal Cassandra database that is deployed with Pega Platform. By using compression, you reduce the size of the data written to disk, and increase read and write throughput.


Starting in Pega Platform version 8.6, the use of an internal Cassandra database is deprecated. On-premises and client-managed cloud systems that have been updated from earlier versions of Pega Platform can continue to use Cassandra in embedded mode. However, to ensure future compatibility, do not create any new environments using embedded Cassandra.

The default compression settings ensure the highest performance.

Configure node-to-node 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 compress all node-to-node compression (both inter-data center and intra-data center), set the value of the dnode/yaml/internode_compression property to ALL.
    Note: This is the default setting for node-to-node compression.
  • If you want to compress only inter-data center traffic, set the value of the dnode/yaml/internode_compression property to DC.
  • If you do not want to use node-to-node compression, set the value of the dnode/yaml/internode_compression property to NONE.
