Brandon Williams commented on CASSANDRA-4023: --------------------------------------------- bq. (Maybe it's time to add random vs sequential speed ratio as a setting, which at least is general enough to be useful in other places.) This sounds like a good idea, we're never going to strike a balance that's sufficient between SSD and rotational media without a knob to turn. > Batch reading BloomFilters on startup > ------------------------------------- > > Key: CASSANDRA-4023 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4023 > Project: Cassandra > Issue Type: Improvement > Reporter: Joaquin Casares > Labels: datastax_qa > > 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.
