Aleksey Yeschenko updated CASSANDRA-6953: ----------------------------------------- Reviewer: Sylvain Lebresne Fix Version/s: 2.1 beta2 > Optimise CounterCell#reconcile > ------------------------------ > > Key: CASSANDRA-6953 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6953 > Project: Cassandra > Issue Type: Improvement > Reporter: Aleksey Yeschenko > Assignee: Aleksey Yeschenko > Priority: Minor > Fix For: 2.1 beta2 > > > Can't have CASSANDRA-6506 in 2.1, but we can get *some* of the benefit by > optimising CounterCell#reconcile() as it is. > Specifically, if one context is a superset of the other one, there is no need > to allocate a BB for the resulting context and merge them - we can just > return the superset context. With 2.1 producing global shards exclusively, > this would minimize allocations by a lot for reads from multiple sstables. -- This message was sent by Atlassian JIRA (v6.2#6252)
