  16. def stream(): Resource[F, Stream[F, CommittableRecord[F]]]

    Runs a KCL Consumer as an fs2.Stream

    Runs a KCL Consumer as an fs2.Stream

    returns

    fs2.Stream that manages the lifecycle of the KCL Consumer

  17. def streamWithDeferredListener(stateToCompleteOn: WorkerState = WorkerState.STARTED): Resource[F, StreamAndDeferred[F]]

    Runs a KCL Consumer in the background as a Resource.

    Runs a KCL Consumer in the background as a Resource. This exposes the WorkerState which can be used as a means to determine if the KCL Consumer is running. A common use case for this is to service healthcheck endpoints when running these in an orchestration service (e.g. Kubernetes or AWS ECS) or running tests that require the consumer to be up before an assertion is checked.

    Unlike streamWithRefListener, this method uses a Deferred instance. This is useful when you only need to react when the KCL has reached a specific state 1 time (e.g. wait to produce to a stream until the consumer is started)

    stateToCompleteOn

    WorkerState to expect when completing the Deferred. Default is STARTED.

    returns

    Resource containing an fs2.Stream and Deferred

  18. def streamWithRefListener(): Resource[F, StreamAndRef[F]]

    Runs a KCL Consumer as an fs2.Stream.
