Thanks Adam,

OK, then maybe Couchdb isn't what I'm looking for because I really need to 
purge deleted documents.

I'm not using replication, and my data has a life of a couple of days, 
maximum. So I have a lot of data coming in, being updated, and then being 
deleted. All those old deleted documents are just going to get in the way.

Hi Geoff,

Hmm, no … purge does not work at the clustered database level in the 2.0 
release. It looks like we may have failed to document this change beyond the 
API response that you got. There are some subtleties in how we have to 
manage that operation in a cluster. For example, if you happen to purge a 
document while only two replicas out of three are online, the third one may 
ultimately get re-propagated to the other two shards at a later date.

I know some folks are working on adding this capability back in to the 
clustered API, but until that work lands if you absolutely need to purge 
documents you can navigate to the shard-level API on a different port and 
execute the purge request there. That’s not for the faint of heart, though. 
Cheers,

Adam
