--------------------------------------
Skill Level: Committers Level (Medium to Hard)
> Allow a view to use other views internally
> ------------------------------------------
>
> Key: COUCHDB-877
> URL: https://issues.apache.org/jira/browse/COUCHDB-877
> Project: CouchDB
> Issue Type: New Feature
> Components: JavaScript View Server
> Affects Versions: 1.0.1
> Reporter: Adriaan vk
>
> It is great that couchdb can store any document on which you can query. After
> storing tons of documents, it is a common task to 'play' around with the data
> by filtering on any document-item.
> For playing around, you can use temp views rather then creating every
> possible filtering view. But since temp views perform bad in a big storage,
> those needs to be speeded up:
> - Allow a temp view to be created on top of other views. This even allows
> complex search queries like '> x' or 'contains y', since the set to page
> through is quite small. Even any kind of sorting can be done using temp views.
> - For this you need also an execution plan for which view you can use best
> for a first filtering
> - Optimize a temp view when i add things like limit. If i send a tempview to
> the server with limit 10, currently all docs are processed, while this is not
> needed.
> - Temp views will also speed up the database, since otherwise we have to
> persist all possible views, which needs to be updated by each insert. (The
> same issue as you have in regular databases where you are not creating tons
> of indexes because of performance)
> If this can be realized, this would improve the usability of couchdb hugh!
> You can create complex (sub)filtering and sorting on hugh document stores.
> You also can create (temp)views on user request, speeding up the whole
> process. This even is required for me to be able to use this great document
> storage tool.
> Any suggestions are welcome!
