[jira] [Commented] (COUCHDB-1243) Compact and copy feature that resets changes

["Robert Newson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-1243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13081235#comment-13081235 ] 

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 trivial.

> 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.
