Amazon Keyspaces (for Apache Cassandra)—a scalable, serverless, highly available, and fully managed Apache Cassandra-compatible database service, now supports the Murmur3Partitioner.
Partitioners create a numeric token using a hashed value of the partition key. Keyspaces uses this token to distribute data across nodes. Clients can also use these tokens in SELECT operations and WHERE clauses to optimize read and write operations. The Murmur3Partitioner is the preferred partitioner for Cassandra developers. For existing keyspaces, you can safely change your account-level partitioner at any time. You do not need to reload your Amazon Keyspaces data when you change the partitioner setting. Clients will automatically use the new partitioner setting the next time they connect.
