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.
