Kurt Greaves created CASSANDRA-14291: ----------------------------------------
Summary: Nodetool command to recreate SSTable components Key: CASSANDRA-14291 URL: https://issues.apache.org/jira/browse/CASSANDRA-14291 Project: Cassandra Issue Type: Improvement Reporter: Kurt Greaves Need a JMX/Nodetool command to recreate components for SSTables without re-writing the data files. Possible implementation idea: Create a {{nodetool (recreate|regen)component}} command that would enable you to recreate specific components of an SSTable, and also allow specifying SSTables or columnfamilies. I'd say a flag for a list of components and a flag for SSTables with keyspace.columnfamilies as positional arguments would work Alternatively this could become part of upgradesstables, but would likely make that command a bit bloated. Background: In CASSANDRA-11163 we changed it so summaries and bloomfilters were not regenerated or persisted on startup. This means we would rely on compactions/upgrades to regenerate the bloomfilter (or other components) after a configuration change. While this works, it's pretty inefficient on large tables just because you changed the bloomfilter size or summary chunk sizes. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
