[jira] [Created] (CASSANDRA-5662) Wasted work in
StorageService.initClient()
Adrian Nistor created CASSANDRA-5662:
----------------------------------------
Summary: Wasted work in StorageService.initClient()
Key: CASSANDRA-5662
URL: https://issues.apache.org/jira/browse/CASSANDRA-5662
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.2.5
Environment: any
Reporter: Adrian Nistor
Attachments: patch.diff
The problem appears in version 1.2.5 and in revision 26018be2.. I
attached a one-line patch that fixes it.
In method "StorageService.initClient", the loop over
"Gossiper.instance.getLiveMembers()" should break immediately after
"isUp" is set to "true". All the iterations after "isUp" is set to
"true" do not perform any useful work, at best they just set "isUp"
again to "true".
Method "getCompactedRow" in class "ParallelCompactionIterable.Reducer"
has a similar loop (over "rows"), and this loop breaks immediately
after "inMemory" is set to "false", just like in the proposed patch.
Other methods (e.g., "GroupByPrefix.count",
"SecondaryIndex.buildIndexAsync") also have similar loops with similar
breaks, just like in the proposed patch.
