Subject [jira] [Commented] (COUCHDB-714) Support document namespaces for more efficient view generation
Date Tue, 25 Jun 2013 23:34:20 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-714?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13693495#comment-13693495
] 

Alexander Shorin commented on COUCHDB-714:
------------------------------------------

Partially, this could be done by using COUCHDB-1373 feature. Each node has his own custom
suffix and there is some view, that emits rows by their node uuid suffix. To easily split
suffix from other _id part, it's possible to have it with leading marker character like `@my-local-couch-ns`.

> I would like to suggest a new, possibly optional, reserved attribute to specify a namespace
for documents. Design documents with this attribute ('_ns' perhaps) would only consider documents
with the same namespace during view generation.
> Obviously, separating documents into several nodes is a workable alternative, but keeping
docs in the same node, with namespaces, would preserve the ability to use the 'include_docs
by _id' feature.
> There may also be cause to include a _namespaces document for mapping namespace names
to URIs.
