- BlockingEnvelopeMap is a helper class for SystemConsumer implementations.
- Samza's poll() requirements make implementing SystemConsumers somewhat
- tricky. BlockingEnvelopeMap is provided to help other developers write
- SystemConsumers. The intended audience is not those writing Samza jobs, but
- rather those extending Samza to consume from new types of stream providers
- and other systems.
- </p>
- 
- <p>
- SystemConsumers that implement BlockingEnvelopeMap need to add messages using
- add (or addAll), and update noMoreMessage using setIsAtHead. The
- noMoreMessage variable is used to determine whether a SystemStreamPartition
- is "caught up" (has read all possible messages from the underlying system).
- For example, with a Kafka system, noMoreMessages would be set to true when
- the last message offset returned is equal to the offset high watermark for a
- given topic/partition.
