Mike Percy updated KUDU-452:
----------------------------
Parent: KUDU-423
> Implement data block GC
> -----------------------
>
> Key: KUDU-452
> URL: https://issues.apache.org/jira/browse/KUDU-452
> Project: Kudu
> Issue Type: Sub-task
> Components: tablet
> Affects Versions: M4
> Reporter: Mike Percy
> Assignee: Adar Dembo
> Labels: kudu-roadmap
>
> There is currently no process that deletes data blocks when they are no
> longer used. We need to ensure they are not in use by any scanners before
> they are deleted.
> Once this is implemented, Remote Bootstrap / catch-up will also need to be
> able to prevent GC of blocks being copied. Some kind of anchoring or timeout
> will be needed.
