> 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.
