Vijay resolved CASSANDRA-4358. ------------------------------ Resolution: Not A Problem {quote} But at least doing it for one source and throwing the others into L0 would be a decent optimization. {quote} Sure that reduces fragmentation. In-fact we stream only from 2 nodes but the range requests are fragmented we can send one request per node instead of one request per range. (will try this in a different ticket). {quote} Shouldn't the new SEVERITY level in the dsnitch avoid the node until it's done compacting? {quote} it should, but still the compaction can run forever with throttle enabled. We could run into issues when another node goes down. {quote} So imo it will be much less fragile to let user do that and start thrift once they consider the new node "stable" enough rather than trying to do that automatically. {quote} It is scriptable both un-throttling and stopping thrift traffic. Let me close this ticket and try that route (Priam). > Delay Joining the ring until bootstrap and its compaction completes > ------------------------------------------------------------------- > > Key: CASSANDRA-4358 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4358 > Project: Cassandra > Issue Type: Improvement > Components: Core > Affects Versions: 1.1.1, 1.2 > Reporter: Vijay > Priority: Minor > Fix For: 1.2 > > > LCS adds a lot of small SST's while bootstrapping a node (after streaming), > followed by a large amount of compactions. > We might want to do the following to speedup the compaction and reduce the > impact to the incoming traffic: > 1) Delay the node from joining the ring and wait until the node settles down > with compactions. > 2) Un-throttle the compactions and do it ASAP. > 3) Once the node settles down we can enable thrift and join the ring. > at the Least it might be better for us to avoid thrift traffic until the > compaction completes. -- This message is automatically generated by JIRA.
