- For every Decision Data Store (DDS) node, add the following dynamic system
- In the Pega-Engine ruleset, set the same number of concurrent compactors by adding the prconfig/dnode/yaml/concurrent_compactors/default property with the value that represents the number of CPU cores.
- In the Pega-Engine ruleset, configure the
compaction throughput by adding the
property with the following value: 256.
For more information, see Configuring dynamic system settings.
Determining the most appropriate compaction throughput setting is an iterative process. You can use the nodetool to adjust the compaction throughput for one node at a time, without requiring a node restart. In that case, any changes are reverted after the restart. For more information about the nodetool commands for compaction throughput, see the Apache Cassandra documentation.
- Restart all DDS nodes.For more information, see Managing decision management nodes.
