Subject Re: [VOTE]: Deprecate _update Endpoint
Date Wed, 06 May 2020 15:40:51 GMT
When we looked at some of our internal usage data we found that _update had measurably higher
adoption than the rendering functions, so we didn’t push so hard on deprecating it yet.

I’d feel better about removing this endpoint if there was a clear plan to provide alternative
server-side partial update functionality in a future release. We had some good discussions
in GitHub a while back:

https://github.com/apache/couchdb/issues/1554
https://github.com/apache/couchdb/issues/1559

It’d be good to review those designs and see if we can advance them to the level of an RFC.
I suspect we’re close.
