ShardingEnvelope

final case class ShardingEnvelope[M](entityId: String, message: M) extends Product with Serializable

Default envelope type that may be used with Cluster Sharding.

Cluster Sharding provides a default HashCodeMessageExtractor that is able to handle these types of messages, by hashing the entityId into into the shardId. It is not the only, but a convenient way to send envelope-wrapped messages via cluster sharding.

The alternative way of routing messages through sharding is to not use envelopes, and have the message types themselves carry identifiers.
