  6. def create[E](startingAt: SequencerCounter, identifier: String, member: Member, handler: SerializedEventHandler[E])(implicit traceContext: TraceContext): EitherT[Future, CreateSubscriptionError, SequencerSubscription[E]]

    Create a subscription for an event handler to observe sequencer events for this member.

    Create a subscription for an event handler to observe sequencer events for this member. By connecting from startingAt it is assumed that all prior events have been successfully read by the member (and may be removed by a separate administrative process). Closing the returned subscription should disconnect the handler. If member is unknown by the sequencer a sequencer.errors.CreateSubscriptionError.UnknownMember error will be returned. If the counter is invalid (currently will only happen if counter <0) a sequencer.errors.CreateSubscriptionError.InvalidCounter error will be returned.

    startingAt

    Counter of the next event to observe. (e.g. 0 will return the first event when it is available)

    identifier

    a name to attach to the connection

    member

    Member to subscribe on behalf of.

    handler

    The handler to invoke with sequencer events

    returns

    A running subscription
