Jean-Daniel Cryans updated HBASE-1944:
--------------------------------------

    Attachment: HBASE-1944.patch

This patch adds the new HTD.IS_SYNCED attribute and in HRS I refactored the code that handles the syncs in a method that also checks if the table has to be synced.

> 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.
