Bala Prassanna I updated KAFKA-6690:
------------------------------------
    Description: 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.  (was: We often
encounter use cases where we need to prioritise source topics. If a consumer is listening
more than one topics, 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.)
