yukon created ROCKETMQ-323:
------------------------------

             Summary: Release semaphore after callback being finished for async invoke
                 Key: ROCKETMQ-323
                 URL: https://issues.apache.org/jira/browse/ROCKETMQ-323
             Project: Apache RocketMQ
          Issue Type: Improvement
          Components: rocketmq-client
    Affects Versions: 4.1.0-incubating, 4.0.0-incubating
            Reporter: yukon
            Assignee: yukon
             Fix For: 4.2.0


Currently, the async semaphore will be released before invoking the callback, if the callback is a heavy task which is not recommended, lots of async requests will be queued in `publicExecutor` thread pool, may cause OOM or FGC.
