Subject [jira] [Commented] (CASSANDRA-4761) Async hints delivery
Date Thu, 11 Oct 2012 17:17:03 GMT

Brandon Williams commented on CASSANDRA-4761:
---------------------------------------------

Changed my mind, Jonathan is right.  "break delivery" breaks the while loop, it doesn't 'jump'
to the label.

> Hints delivery to remote DC can take a long time (currently we have 70 ms for each hint).
In our estimates 700 MB of data (stored hints) will be transmitting to remote DC more than
one day (in our case), it's unacceptable for us. We suggest to enter hints delivery using
batch operations. 
> What do you think about it? Is there some facts that won't allow to implement that mechanism?
> I'll try to implement it if you approve and clarify right way.
