Alexey Zotov commented on CASSANDRA-4768:
-----------------------------------------
I'll try to explain my motivation. There is the following use case:
We have a few DCs. One of DCs has been lost connection to others. So we should
store hints for all ranges of data (for all data set) for that DC. Write's
throughput is very high. Amount of stored hints for the lost remote DC grows
very quickly.
We can reduce max_hint_window_size, but we want to keep repair mechanism for
local nodes.
> Add separate max_hint_window_in_ms option for remote data centers

> It would be nice to have possibility to configure hint window size for remote
> dc separately. 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.
