Enis Soztutar commented on HBASE-15131:
---------------------------------------
bq. The #WALs having some limit so that the data size to replay on a recovery
is not too much. So when we have multi WAL, we should take that in to account
and should reduce the # WAL files per group accordingly? Say in 2 WALs, per
group 16 max?
I thought that we have removed that limit.
> Turn on multi-WAL by default

> Something to discuss for 2.0 or even 1.3 or 1.4. Should we turn on multi-WAL
> by default now that it has seen some production use.
> Most of the known issues has been fixed I believe for replication, metrics
> etc. See HBASE-14457.
> Using bounded provider with default 4 (assuming 12 disks). Should we also
> look at the number of disks from datanode dirs and auto-configure?
