final class Murmur2MessageExtractor[M] extends ShardingMessageExtractor[ShardingEnvelope[M], M]
The murmur2 message extractor uses the same algorithm as the default kafka partitioner allowing kafka partitions to be mapped to shards. This can be used with the akka.cluster.sharding.external.ExternalShardAllocationStrategy to have messages processed locally.
Extend Murmur2NoEnvelopeMessageExtractor to not use a message envelope extractor.
