Blake Eggleston updated CASSANDRA-14939:

|[trunk|https://github.com/bdeggleston/cassandra/tree/14939-trunk]|[dtests|https://github.com/bdeggleston/cassandra-dtest/tree/14939]|[circle|https://circleci.com/workflow-run/587857d3-8d7a-4710-906f-010f499d4910]|

This adds {{\-\-cleanup}}, {{\-\-summarize-pending}}, and {{\-\-summarize-repaired}} flags to {{nodetool repair_admin}}. Each of which also accept keyspace/table and range args. To support reporting the min/max repairedAt time for a given token range across restarts, I had to alter the logic for purging old sessions. Finalized sessions will only be deleted if there is a newer session covering it's ranges.

> Incremental repair has a few operational rough spots that make it more difficult to fully automate and operate at scale than it should be.
> * Visibility into whether pending repair data exists for a given token range.
> * Ability to force promotion/demotion of data for completed sessions instead of waiting for compaction.
> * Get the most recent repairedAt timestamp for a given token range.
