Subject [jira] Updated: (HBASE-1944) Add a "is synced" attribute to HTD
Date Fri, 30 Oct 2009 00:30:59 GMT

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.
