> 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.
