> Allow CF to retain deleted rows
> -------------------------------
>
> Key: HBASE-4536
> URL: https://issues.apache.org/jira/browse/HBASE-4536
> Project: HBase
> Issue Type: New Feature
> Components: regionserver
> Affects Versions: 0.92.0
> Reporter: Lars Hofhansl
> Assignee: Lars Hofhansl
> Fix For: 0.94.0
>
> Attachments: 4536-v15.txt, 4536-v16.txt
>
>
> Parent allows for a cluster to retain rows for a TTL or keep a minimum number
> of versions.
> However, if a client deletes a row all version older than the delete tomb
> stone will be remove at the next major compaction (and even at memstore flush
> - see HBASE-4241).
> There should be a way to retain those version to guard against software error.
> I see two options here:
> 1. Add a new flag HColumnDescriptor. Something like "RETAIN_DELETED".
> 2. Folds this into the parent change. I.e. keep minimum-number-of-versions of
> versions even past the delete marker.
> #1 would allow for more flexibility. #2 comes somewhat naturally with parent
> (from a user viewpoint)
> Comments? Any other options?
