What is the current status of CouchDB and hierarchical views? I am not sure if the idea has already been discussed, but it is a feature wich is really needed.
# Scenario We have very big CouchDBs with millions of documents growing fast. There are several types like "date", "tour", "user" and others. "Dates" are growing fast and accessed often. "Users" are growing slow and accessed seldom. When "dates" are accessed everything is fine because the index is updated often and fresh. When users are accessed the on-demand indexer starts and blocks for a long period because hundred thousands new "dates" documents are scanned, which is not needed. If there was a first level view "types" the indexer would just need to scan a few "user" docs and could skip all the "dates" docs to update the "user" index. - Hans
