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: Sylvain Lebresne Fix For: 1.2
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.
