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
