Subject [jira] Commented: (COUCHDB-523) View API POST keys to retrieve multiple docs by key could also allow for multiple 'range' queries, i.e. an array of { startkey: .., endkey: ... } params in the POST

    [ https://issues.apache.org/jira/browse/COUCHDB-523?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12848943#action_12848943

Jamie Talbot commented on COUCHDB-523:
--------------------------------------

I wanted this feature so much, I hacked up a version that appears to do it.  I'm nowhere near
an Erlang or Couch expert, but it seems to do what I want and still be lightning fast so perhaps
it is a solution.  The only changes were made to couch_httpd_view.erl.  General theory of
operation is to pattern match start and end key fields from the Key variable in output_map_view
and output_reduce_view.  I also had to list the restrictions on group_levels for multi-key
documents seeing as they do make sense in this context.

Was pretty much scrambling in the dark, but If that sounds like a sensible approach, and someone
can give me pointers on how to contribute, I'd be happy to attach it here. 

In the meantime, I'll attach my hacked up version of couch_http_view.erl.  I've also included
a diff from version 0.10.1.

> It would be useful if I could do a single POST to a view to retrieve multiple ranges
specified by startkey, endkey.
> The format could be as follows:
> { "ranges": [ { "startkey": "a", "endkey": "c" }, { "startkey":"g", "endkey":"z" } ]
}
