Vijay updated CASSANDRA-3762: ----------------------------- Attachment: 0001-CASSANDRA-3762-v5.patch >>> It means that the method don't return what what it should and should be >>> renamed to *estimate*SerializedSize but as we would to the same for all of >>> the rows in the cache I don't see how it would harm LRU if we do the real >>> calculation. If you are getting hot n keys, it will be making hot keys even more hotter.... renamed. >>> It does not the idea is that the newer cache will delete the older one :) so it is a no op after that.... anyways fixed it just for the sake of it :) >>> What about this one? As we are using estimate not the real value we need to use the serializedSize.... Thats how it was earlier too :) > 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-CASSANDRA-3762-v2.patch, > 0001-CASSANDRA-3762-v3.patch, 0001-CASSANDRA-3762-v4.patch, > 0001-CASSANDRA-3762-v5.patch, 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.
