    A PartitionHub is a special streaming hub that is able to route streamed elements to a dynamic set of consumers.

    A PartitionHub is a special streaming hub that is able to route streamed elements to a dynamic set of consumers. It consists of two parts, a Sink and a Source. The Sink e elements from a producer to the actually live consumers it has. The selection of consumer is done with a function. Each element can be routed to only one consumer. Once the producer has been materialized, the Sink it feeds into returns a materialized value which is the corresponding Source. This Source can be materialized an arbitrary number of times, where each of the new materializations will receive their elements from the original Sink.

Abstract Value Members

  1. abstract def consumerIdByIdx(idx: Int): Long

    Obtain consumer identifier by index

  2. abstract def getConsumerIds: List[Long]

    Sequence of all identifiers of current consumers.

    Sequence of all identifiers of current consumers.

    Use this method only if you need to enumerate consumer existing ids. When selecting a specific consumerId by its index, prefer using the dedicated #consumerIdByIdx method instead, which is optimised for this use case.

  3. abstract def queueSize(consumerId: Long): Int

    Approximate number of buffered elements for a consumer.

    Approximate number of buffered elements for a consumer. Larger value than other consumers could be an indication of that the consumer is slow.

    Note that this is a moving target since the elements are consumed concurrently.

  4. abstract def size: Int

    Number of attached consumers.
