Guozhang Wang commented on KAFKA-6690:
--------------------------------------
[~balaprassanna] Your description on the JIRA seems to be requesting this
feature on the Consumer API, while your comment above is suggesting adding it
on the Streams API (note the Streams client actually has embedded Consumer
client internally). Which type of client are you really thinking about?
> Priorities for Source Topics

> Key: KAFKA-6690
> URL: https://issues.apache.org/jira/browse/KAFKA-6690
> Project: Kafka
> Issue Type: New Feature
> Components: streams
> Reporter: Bala Prassanna I
> Assignee: Nick Afshartous
> Priority: Major
>
> We often encounter use cases where we need to prioritise source topics. If a
> consumer is listening more than one topic, say, HighPriorityTopic and
> LowPriorityTopic, it should consume events from LowPriorityTopic only when
> all the events from HighPriorityTopic are consumed. This is needed in Kafka
> Streams processor topologies as well.
