Julian Reschke commented on OAK-11444:
--------------------------------------
I'm a bit concerned here, because this introduces a new document store
collection, which has never happened before.
We need to understand what that means for document store implementations other
than for MongoDB. And for tooling etc. Also, this would need to be documented
properly.
Any chance that this information could just go into SETTINGS???
> [full-gc] Save document id and empty properties names before deletion

> Key: OAK-11444
> URL: https://issues.apache.org/jira/browse/OAK-11444
> Project: Jackrabbit Oak
> Issue Type: Story
> Components: mongomk
> Reporter: Daniel Iancu
> Priority: Major
>
> Store document ID and empty properties names into a dedicated *_bin*
> collection
> before physically deletion from Mongo nodes collection during full gc.
> Motivation behind this change is that in case of accidentally deleting data
> that should have not been deleted (not garbage) this `log` of removed
> documents and properties will help the complete restoration from backup.
> A separate collection was preferred instead of logging to files because is
> more reliable. Logs usually needs to be exported to platform like Splunk and
> the process does not guarantee that all logs are saved.
> The data saved in *_bin* collection is temporary, the cleaning can be done
> via setting document TTL or by using an external job to remove it.
