Vijay commented on CASSANDRA-3762: ---------------------------------- >>> By the way, I forgot to ask you if you dropped page cache before running >>> second test? No it is basically a average of multiple runs.... :) Without any additional writes... start and immediatly stop and compare the logs... both tests are the same. Again it is on my laptop. > AutoSaving KeyCache and System load time improvements. > ------------------------------------------------------ > > Key: CASSANDRA-3762 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3762 > Project: Cassandra > Issue Type: Improvement > Components: Core > Affects Versions: 1.2 > Reporter: Vijay > Assignee: Vijay > Priority: Minor > Fix For: 1.2 > > Attachments: 0001-SavedKeyCache-load-time-improvements.patch > > > CASSANDRA-2392 saves the index summary to the disk... but when we have saved > cache we will still scan through the index to get the data out. > We might be able to separate this from SSTR.load and let it load the index > summary, once all the SST's are loaded we might be able to check the > bloomfilter and do a random IO on fewer Index's to populate the KeyCache. -- This message is automatically generated by JIRA.
