Anoop Sam John commented on HBASE-23634:
----------------------------------------
We can explore all these [~zghao].. Me and Ram were discussing yday. As from
a Cloud storage front, we would like to avoid renames as much as possible :-)
Directly write HFile under CF, the issue is making the file available
atomically. What if the split is stopped in between. (WAL split RS died)..
Also there may be other systems seeing directly the files under CF (Like
offline compaction tool). How we can give a consistent view of the CF files to
these other systems. So this is not a simple change but very involved. But
for sure lets discuss and propose a solution to this.
There was another jira raised some time back on flushing the file directly
under CF. Forgot the jira id.
> Enable "Split WAL to HFile" by default
