Managing Cassandra as the source of decision management data

Pega Platform operates Apache Cassandra as the underlying storage system for the Decision Data Store (DDS). Cassandra is an open source, column-oriented, and fault-tolerant database that handles large data workloads across multiple nodes. The following chapter provides guidelines on how to manage, maintain, and run Cassandra nodes as part of Decision Strategy Manager. It also provides procedures for optimizing Cassandra operations and lists the tools that you can use to perform such optimizations in Pega Platform and outside.
