Subject [jira] [Updated] (CASSANDRA-4049) Add SSTable components required by new DSE CFS compaction strategy
Date Wed, 14 Mar 2012 17:34:39 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-4049?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Piotr Kołaczkowski updated CASSANDRA-4049:
------------------------------------------

    Description: 
CFS compaction strategy coming up in the next DSE release needs to store some important information
in Tombstones.db and RemovedKeys.db files, one per sstable. However, currently Cassandra issues
warnings when these files are found in the data directory. Additionally, when switched to
SizeTieredCompactionStrategy, the files are left in the data directory after compaction.

The attached patch adds new components to the Component class so Cassandra knows about those
files.
