Specified by:

readFrom in interface Streamable

setShardId

public DeleteRequest setShardId(ShardId shardId)

Override this method from ReplicationAction, this is where we are storing our state in the request object (which we really shouldn't do). Once the transport client goes away we can move away from making this available, but in the meantime this is dangerous to set or use because the DeleteRequest object will always be wrapped in a bulk request envelope, which is where this *should* be set.

Overrides:

setShardId in class ReplicationRequest<DeleteRequest>
