Query Class

Query Class

Note: This API is now obsolete.

Message send to particular SQL-based journal IActorRef. It may be parametrized using set of hints. SQL-based journal will respond with collection of QueryResponse messages followed by QuerySuccess when request succeed or the QueryFailure message when request has failed for some reason. Since SQL journals can store events in linearized fashion, they are able to provide deterministic set of events not based on any partition key. Therefore query request don't need to contain partition id of the persistent actor.
