-----------------------------------------
Summary: 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?
