> I am thinking adding a new flag to bookkeeper#addEntry(..., Boolean sync). So
> the application can control whether to sync or not for individual entries.
> - On the write protocol, adding a flag to indicate whether this write should
> sync to disk or not.
> - On the bookie side, if the addEntry request is sync, going through original
> pipeline. If the addEntry disables sync, complete the add callbacks after
> writing to the journal file and before flushing journal.
> - Those add entries (disabled syncs) will be flushed to disks with subsequent
> sync add entries.
> There is already a discussion in mail thread, here this ticket could gather
> ideas, and provide the discussion materials
