Robert Coli commented on CASSANDRA-5727: ---------------------------------------- Anecdotally, many people on @cassandra-user/#cassandra have been bitten by the current 5mb size. The types of negative experiences they have seem to relate to too many SSTables for "small" or "medium" data sizes. Even a relatively naive doubling of this default to 10mb seems likely to be a win for most of these users. > Evaluate default LCS sstable size > --------------------------------- > > Key: CASSANDRA-5727 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5727 > Project: Cassandra > Issue Type: Task > Components: Core > Reporter: Jonathan Ellis > Assignee: Daniel Meyer > > What we're not sure about is the effect on compaction efficiency -- > larger files mean that each level contains more data, so reads will > have to touch less sstables, but we're also compacting less unchanged > data when we merge forward. > So the question is, how big can we make the sstables to get the benefits of > the > first effect, before the second effect starts to dominate? -- This message is automatically generated by JIRA.
