---------------------------
> Reduce lock granularity for putMessage
> --------------------------------------
>
> Key: ROCKETMQ-91
> URL: https://issues.apache.org/jira/browse/ROCKETMQ-91
> Project: Apache RocketMQ
> Issue Type: Improvement
> Affects Versions: 4.1.0-incubating
> Reporter: dongeforever
> Assignee: dongeforever
> Fix For: 4.1.0-incubating
>
>
> CommitLog putMessage has a lock as:
> lockForPutMessage()
> ....
> releasePutMessageLock()
> The logic inside the lock includes two main operations:
> 1 encode the message
> 2 write to the PageCache.
> However, we can take the first operation(encode message) out from the lock to achieve better performance.
