Is there any side effects for MULTI WAL support in hbase?

[#1]

Hi everyone,

I have have hbase cluster with hadoop as storage, I have planned to use MULTI WAL support to hbase to increase write efficiency. But before that i wanted to know is there any side effects to read by using MULTI WAL support.

If not why hbase disabled Multi WAL support by default?

Anyone please explain me.....

MultiWAL is a community feature and is not supported by HDP. If you're not on HDP, you can try the feature but your mileage will vary. Have you Considered placing WAL on SSD?

Yes we are using SSDs, Is mileage is the only thing affected by multi WAL feature?
