Subject Re: Is it possible to bring back optional old all-or-nothing behaviour?
Date Thu, 22 Dec 2011 16:36:34 GMT
The all_or_nothing option (both old and new semantic) are,
respectively, impossible or very hard, to achieve in a cluster.

I would like to see all_or_nothing removed entirely in CouchDB 2.0.
