Josh McKenzie updated CASSANDRA-17789:
--------------------------------------
Test and Documentation Plan: No new testing; relying on current testing
functionality to ensure existing scrub/verify logic works.
Status: Patch Available (was: Open)
> Extend nodetool verify with functionality to detect partitions with duplicate
> keys
> ----------------------------------------------------------------------------------
>
> Key: CASSANDRA-17789
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17789
> Project: Cassandra
> Issue Type: New Feature
> Components: Tool/nodetool
> Reporter: Josh McKenzie
> Assignee: Josh McKenzie
> Priority: Normal
>
> We've seen instances where, during upgrades across major versions and in
> mixed version clusters, we end up with data in a table that has duplication
> of primary keys. This is obviously an illegal state and being able to quickly
> scan for this and log partition keys for which we're seeing this state has
> proven quite useful.
> It's a fairly small change to verify/scrub to integrate this extra
> functionality.
