The only problem is that the queues in RocketMQ (equivalent to partitions in Kafka) are identified by a 3-tuple like MessageQueue(topic, broker, queueId). It is difficult to implement partition level consumer of RocketMQ since Pinot assumes partitionId as integer. -- This is an automated message from the Apache Git Service.
