Subject [jira] [Commented] (COUCHDB-1254) Document design and view options
Date Fri, 19 Aug 2011 16:44:27 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1254?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13087792#comment-13087792

Paul Joseph Davis commented on COUCHDB-1254:
--------------------------------------------


{
    "_id": "_design/foo",
    "options": {"include_design": true, "local_seq": true},
    "views": {
        "bar": {
            "map": "function(doc) {...}",
            "options": {"collation": "raw"}
        }
    }
}


The options at the top level affect the documents that get sent to the map functions for this
design doc. include_design: true means that design docs are passed to the map function. local_seq:
true means that each doc has a magical _local_seq attribute that reflects their local update
seq.

The collation: "raw" option will let views use raw Erlang collation instead of UCA collation
which can be a noticeable speed improvement.

> Off the back of COUCH-1252, I've just discovered there are such things as design options
and view options, including local_seq and include_design. Could somebody who knows what they
do document them somewhere?
