HashCodeMessageExtractor
Companion object HashCodeMessageExtractor
abstract class HashCodeMessageExtractor extends MessageExtractor
Convenience implementation of ShardRegion.MessageExtractor that
construct shardId based on the hashCode of the entityId. The number
of unique shards is limited by the given maxNumberOfShards.
