Subject [jira] [Commented] (CASSANDRA-12671) Support changing hinted handoff throttle in real time
Date Mon, 05 Dec 2016 18:22:58 GMT


Aleksey Yeschenko commented on CASSANDRA-12671:

Speaking of {{TokenMetadata.getAllEndpoints()}}. There are a few cases where we only use it
for size. They should all be replaced with a new method in {{TokenMetadata}} that would just
get the counts (think {{return enpointToHostIdMap.size()}}).

Can you open a new JIRA to add the new method, and replace all {{getAllEndpoints().size()}}
calls with it? I'll review. Thanks.

> Problem: currently the sethintedhandoffthrottlekb takes effect when current hints handoff
tasks finish, and then applies to next task, which could take hours for big node. 
> I think it would be great to change the hinted handoff throttle in real time, which means
it takes effect immediately.
