Jonathan Ellis updated CASSANDRA-4180: -------------------------------------- Reviewer: yukim (was: slebresne) > Remove 2-phase compaction > ------------------------- > > Key: CASSANDRA-4180 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4180 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Sylvain Lebresne > Assignee: Jason Brown > Labels: compaction > Fix For: 1.3 > > > LazilyCompactedRow reads all data twice to compact a row which is obviously > inefficient. The main reason we do that is to compute the row header. > However, CASSANDRA-2319 have removed the main part of that row header. What > remains is the size in bytes and the number of columns, but it should be > relatively simple to remove those, which would then remove the need for the > two-phase compaction. -- This message is automatically generated by JIRA.
