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 use temp views, but since those 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!
