Giampaolo reassigned CASSANDRA-11516: ------------------------------------- Assignee: Giampaolo > Make max number of streams configurable > --------------------------------------- > > Key: CASSANDRA-11516 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11516 > Project: Cassandra > Issue Type: New Feature > Reporter: Sebastian Estevez > Assignee: Giampaolo > Labels: lhf > > Today we default to num cores. In large boxes (many cores), this is > suboptimal as it can generate huge amounts of garbage that GC can't keep up > with. > Usually we tackle issues like this with the streaming throughput levers but > in this case the problem is CPU consumption by StreamReceiverTasks > specifically in the IntervalTree build -- > https://github.com/apache/cassandra/blob/cassandra-2.1.12/src/java/org/apache/cassandra/utils/IntervalTree.java#L257 > We need a max number of parallel streams lever to hanlde this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
