-----------------------------------------
Assignee: Liquan Pei (was: Ewen Cheslack-Postava)
> Connect tasks should not share a producer
> -----------------------------------------
>
> Key: KAFKA-3847
> URL: https://issues.apache.org/jira/browse/KAFKA-3847
> Project: Kafka
> Issue Type: Improvement
> Components: KafkaConnect
> Affects Versions: 0.10.0.0
> Reporter: Ewen Cheslack-Postava
> Assignee: Liquan Pei
> Priority: Critical
> Fix For: 0.10.1.0
>
>
> Currently the tasks share a producer. This is nice in terms of potentially
> coalescing requests to the same broker, keeping port usage reasonable,
> minimizing the # of connections to brokers (which is nice for brokers, not so
> important for connect itself). But it also means we unnecessarily tie tasks
> to each other in other ways -- e.g. when one needs to flush, it we
> effectively block it on other connector's data being produced and acked.
> Given that we allocate a consumer per sink, a lot of the arguments for
> sharing a producer effectively go away. We should decouple the tasks by using
> a separate producer for each task (or, at a minimum, for each connector's
> tasks).
