WriteAck

case class WriteAck(processorId: Int, channelId: Int, ackSequenceNr: Long) extends Product with Serializable

Instructs a Journal to write an acknowledgement. An acknowledgement refers to a previously written input Message and a Channel. Output Messages (that an Eventsourced processor emits to a channel during processing of that input message) are ignored by that channel if an acknowledgement exists for that input message and channel. This mechanism prevents redundant message delivery to channel destinations during event message replay.

processorId

id of the Eventsourced processor that emitted the output message to the channel.

channelId

id of the channel that received the output message from the Eventsourced processor.

ackSequenceNr

sequence number of the input message.
