Jean-Daniel Cryans commented on HBASE-1944:
-------------------------------------------
I just tested this patch on a cluster, I get 1300 incrCol/sec with a single
threaded client on a table that doesn't sync. I killed -9 the RS a couple of
times and even with optional sync every 100ms I lose only 1-2 edits.

> At SU we have a case where we'd like to be able to, by default, sync every
> appended edit but for some tables have the control to disable their sync. You
> could then rely on other tables like .META. to do syncs, the optional log
> syncer timer down in LogSyncer and user tables that are always synced. For
> example, set a 10ms timer on the log syncer so that in the worse case you
> lose 10ms of non-catalog edits.
