Subject [jira] [Commented] (COUCHDB-1243) Compact and copy feature that resets changes
Date Mon, 08 Aug 2011 22:00:27 GMT


Robert Newson commented on COUCHDB-1243:

The difference is the removal of all the _deleted stubs which are critical to the correct
operation of CouchDB replication. As such, I'm -1 on the idea.

That said, I'd be +1 on add /db/_export and /db/import entry points that make backup/restore

>          Components: Database Core
>    Affects Versions: 1.0.1, 1.1
>         Environment: Ubuntu, but not important

> After running db and view compaction on a 7K doc db with 6+ mio. changes - it takes up
0.8 GB. If copying the same documents to a new db (get and bulk insert) - the same date with
7K changes takes up 40 mb. That is a huge difference. Has been verified on 2 db's that the
difference is more than 65 times the size of data.
> A "Compact and copy" feature that copies only documents, and resets the changes for at
db would be very nice to try and limit the disk usage a little bit. (Our current test environment
takes up nearly 100 GB... )
> I've attached the dump load php script for your convenience.
