Subject [jira] [Commented] (CASSANDRA-4768) Add separate max_hint_window_in_ms option for remote data centers
Date Mon, 08 Oct 2012 15:10:02 GMT


Brandon Williams commented on CASSANDRA-4768:

If you lose a DC and exceed the hint window you'll have to repair... which would fix any local
damage as well, so it doesn't really matter if you have a longer local hint window since you
have to repair anyway.

It will allow to prevent accumulating of big amount of data for remote dc and long hints delivery
as the result of it.
> I suggest to add max_hint_window_for_remote_dc_in_ms option.
