[jira] [Updated] (CASSANDRA-2576) Rewrite into new file post
streaming
[ https://issues.apache.org/jira/browse/CASSANDRA-2576?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stu Hood updated CASSANDRA-2576:
--------------------------------
Attachment: 0002-Rebuild-into-a-new-file-to-minimize-magic.txt
0001-Don-t-depend-on-a-byte-for-byte-match-for-SSTable-rebu.txt
Patch to use SSTableWriter during rebuilding for commutative column families.
This replaces CASSANDRA-2336 as a blocker for 674, because we don't need to version the builder, due to reading from (versioned) iterators and using a writer which will write the most recent version.

> Commutative/counter column families use a separate path to rebuild sstables post streaming, and that path currently rewrites the data within the streamed file. While this is great for space efficiency, it means a duplicated code path for writing sstables, which makes it more difficult to make changes like #674.
