Subject Potential Change in Kafka's Partition Assignment Semantics when Subscription Changes
Date Tue, 26 Jul 2016 00:20:03 GMT
Hello,

We have started a KIP under the Kafka project that proposes a fix for an 
inconsistency in how partition assignments are currently handled in Kafka 
when the consumer changes subscription. Note that this applies to new 
consumer only.
The KIP can be found here: 
https://cwiki.apache.org/confluence/display/KAFKA/KIP-70%3A+Revise+Partition+Assignment+Semantics+on+New+Consumer%27s+Subscription+Change

The compatibility section (
https://cwiki.apache.org/confluence/display/KAFKA/KIP-70%3A+Revise+Partition+Assignment+Semantics+on+New+Consumer%27s+Subscription+Change#KIP-70:RevisePartitionAssignmentSemanticsonNewConsumer'sSubscriptionChange-Compatibility,Deprecation,andMigrationPlan
) describes impacted users.

We would like to know if any Apache Storm user would be affected by this 
change. Thanks.
 
Regards,
--Vahid
