ServerStreamletLogic

abstract class ServerStreamletLogic extends AkkaStreamletLogic

Extends a StreamletLogic. provides access to a containerPort so that it is possible to start a TCP server inside an AkkaStreamlet which will be exposed through an endpoint in Kubernetes.

    Signals that the streamlet is ready to process data. signalReady completes the StreamletExecution.ready future. When a streamlet is run using the testkit, a StreamletExecution is returned. StreamletExecution.ready can be used for instance to wait for a server streamlet to signal that it is ready to accept requests.

    Creates a sink for publishing records to the outlet. The records are partitioned according to the partitioner of the outlet.

  49. def sourceWithOffsetContext[T](inlet: CodecInlet[T]): SourceWithOffsetContext[T]

    This source emits T records together with the offset position as context, thus makes it possible to commit offset positions to Kafka (as received through the inlet).

    This source emits T records together with the offset position as context, thus makes it possible to commit offset positions to Kafka (as received through the inlet). This is useful when "at-least once delivery" is desired, as each message will likely be delivered one time, but in failure cases, they can be duplicated.

    It is intended to be used with sinkWithOffsetContext(outlet: CodecOutlet[T]) or Committer.sinkWithOffsetContext, which both commit the offset positions that accompany the records, read from this source. sinkWithOffsetContext(outlet: CodecOutlet[T]) should be used if you want to commit the offset positions after records have been written to the specified outlet. The inlet specifies a cloudflow.streamlets.Codec that will be used to deserialize the records read from Kafka.
