> In the multiple raft group use case, multiple raft logs will be written at 
> the same time.  If there are multiple disk devices available in the server, 
> it is better to have multiple storage directories configured in different 
> disk devices for a better performance.
> We may change the server conf {{raft.server.storage.dir}} to take a list of 
> directories so that the server could assign them to individual group.
