Assigning partitions manually has no relation with consumer groups. I mean ... a consumer doesn't need to be part of a consumer group (so specifying group.id) for having a partition assigned manually. ________________________________ From: venkata sastry akella <akel...@gmail.com> Sent: Thursday, July 13, 2017 7:09:33 PM To: dev@kafka.apache.org Subject: Clarification on KafkaConsumer manual partition assignment
KafkaConsumer API doc has the following statement. "Note that it isn't possible to mix manual partition assignment (i.e. using assign <https://kafka.apache.org/0100/javadoc/org/apache/kafka/clients/consumer/KafkaConsumer.html#assign(java.util.Collection)>) with dynamic partition assignment through topic subscription (i.e. using subscribe <https://kafka.apache.org/0100/javadoc/org/apache/kafka/clients/consumer/KafkaConsumer.html#subscribe(java.util.Collection)> )." Question: Does this statement applies to only one consumer group or multiple consumer groups ? Meaning, can one consumer group has manual assignment and other consumer group has automatic assignment ? OR if atleast one consumer group has manual assignment, then automatic assignment doesnt work for any other consumer group also ? Thanks for clarifying this.
