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=12849133#action_12849133

Nikita Nemkin commented on COUCHDB-523:
---------------------------------------

This is a very useful feature when indexing spatial data using z-order curve, hilbert curve
etc. Queries to such indexes translate directly to a bunch of B-tree range queries (up to
hundreds of ranges, depending on implementation).

> 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" } ]
}
