Yuki Morishita updated CASSANDRA-4023: -------------------------------------- Attachment: cassandra-1.0-4023-v3.txt Attaching v3, which is slightly modified from v2 and comes with test. > Improve BloomFilter deserialization performance > ----------------------------------------------- > > Key: CASSANDRA-4023 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4023 > Project: Cassandra > Issue Type: Improvement > Components: Core > Affects Versions: 1.0.1 > Reporter: Joaquin Casares > Assignee: Yuki Morishita > Priority: Minor > Labels: datastax_qa > Fix For: 1.0.9, 1.1.0 > > Attachments: 4023.txt, cassandra-1.0-4023-v2.txt, > cassandra-1.0-4023-v3.txt > > > The difference of startup times between a 0.8.7 cluster and 1.0.7 cluster > with the same amount of data is 4x greater in 1.0.7. > It seems as though 1.0.7 loads the BloomFilter through a series of reading > longs out in a multithreaded process while 0.8.7 reads the entire object. > Perhaps we should update the new BloomFilter to do reading in batch as well? -- This message is automatically generated by JIRA.
