Key: ROCKETMQ-294
URL: https://issues.apache.org/jira/browse/ROCKETMQ-294
Project: Apache RocketMQ
Issue Type: Improvement
Components: rocketmq-client
Reporter: yukon
Assignee: yukon
Fix For: 4.2.0-incubating
*Motivations*
Current flow control strategy only support on Queue level, each message queue
can cache 1000 message by default.
When lots of message queue are assigned to one consumer instance, the consumer
will cache too many messages, may cause OOM exception.
On the other hand, only control the message amount is not enough, should
support do flow control on the number and size dimensions, on Topic and Queue
level.
