RIP-2 Multiple directories support for commitLog storage
Dear Apache RocketMQ Community
I would like to propose a new feature for Apache RocketMQ: multiple
directories support for commitLog storage.
Details is in the RIP file :
https://docs.google.com/document/d/1jTPCzyWChc1RVQIAg7x86IVcaWKgAqEwDIODkZhhNuA/edit?usp=sharing
Any suggestions and comments are welcome!
Best regards
Haiting Jiang

Any discussion on it ? If not, I would like to discard and archive it. IMO, it is a good start from the newer storage introduced from the 5.0.

Data sync is done by HAService, where all commit log data is transferred
through *CommitLog.mappedFileQueue.*
Although we changed the underlying file location of the commit log files,
nothing is changed when we read/write data through mappedFileQueue.
So we the storePath of master and slave brokers can even be set differently.

The RIP may affect Data Sync, Is there a evaluation?
