Module partitioner

Partitioners are algorithms that can compute token for a given partition key, ultimately allowing optimised routing of requests (such that a request is routed to replicas, which are nodes and shards that really own the data the request concerns). Currently, two partitioners are supported:

• Murmur3Partitioner
  • the default partitioner,
  • modified for compatibility with Cassandra’s buggy implementation.
• CDCPartitioner
  • the partitioner employed when using CDC (Change Data Capture).
