Hints handoff is memory intensive

In our 2.1 cluster, I find that hints handoff is using a lot of memory on our proxy nodes, when delivering hints to a data node that was dead for 3+ hours (our hints window is 3 hours). It makes the young gen GC time as long as 2 secs. I'm using 64G max heap size, and 4G young gen size. I'm

Major changes in 3.0, but the big ones involve storage - parent ticket is https://issues.apache.org/jira/browse/CASSANDRA-9427 64G cms heap with 4G new gen is somewhat atypical - would expect g1 at that size, or at the very least a larger new gen to try to avoid promotion which will bring you

Re: Proposal - 3.5.1

@Sylvain - I see what you're saying now on the branches. I suppose a branching strategy like that does give some flexibility to have multiple things in the pipeline so it does give some additional flexibility there. On Mon, Sep 19, 2016 at 9:06 AM Eric Evans wrote:
