Sean Busbey commented on HBASE-15131:
-------------------------------------
I'd like to see some perf numbers on a shipped version of HBase before we make
this the default. IIRC, the benchmarks from HBASE-14457 used a custom backport
on top of 0.98.
I have some numbers from a small test cluster, but I'm not sure how useful such
a small scale is.
> Turn on multi-WAL by default

> Key: HBASE-15131
> URL: https://issues.apache.org/jira/browse/HBASE-15131
> Project: HBase
> Issue Type: New Feature
> Components: wal
> Reporter: Enis Soztutar
> Fix For: 2.0.0, 1.3.0
>
>
> 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?
