Jean-Daniel Cryans commented on HBASE-1939:
-------------------------------------------
Raghu,
Again thanks a lot for spending some time looking at my work.
So the background is that the catalog tables like .META. must never lose any
edits so, even if we sync every 100 edits for some reason, when this catalog
edit comes in we want to make sure it's safely registered.
And you are right, this is not the right place to set force as you pointed out.

> appends. Implementing group commit can help this by being aware of all the
> clients in that queue.
