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.
