Thinking about this, you don't have to get all the database. If you
have the set of keys you are interested in for all the docs eg
[clientName, dateMP1, dateM1]
1. create a design doc '_design/report'
2. create a view that for all types you want, eg 'by_id' and
emit(doc._id, doc)
3. create a
Hi Jan,

I really don't see how that would work, except by getting most of the database
to be returned to the list function and doing set manipulation there...

Sorry, I'll try to be clearer. I should have taken a real case to start with, I

Consider 5 types of documents:

What about a list function?
You can access the request to get query parameters (eg id needed for
the report?) and then you can iterate through the docs and build up
your relationship.
I dont know how fast it will be with the number of docs you have, but
it will be liner time (order n).

I am not sure if I fully understand your use case (however it does sound
intriguing and unusual).
A couple of things stick out in your commentary;
"The data is only weakly relational."
"DB updates are relatively few"
I assume that you are getting data out of your legacy MySQL system
All right; no one should like what they're going to read.
I have a medium-sized MySQL system, which translates to a Couch with about a
million documents of about 20 types. The system would really benefit from a
schema-free design. The data is only weakly relational. Couch would fit really

That would probably cause concurrency problems with legitimate updates. Shame.
That would be very useful functionality.

Is there a way to force a document reindex, like is triggered by an update,
without actually doing the update?
I am trying to do unspeakable things to Couch, but ones that would be very

Hi Neville,
The CouchDB Book has a chapter on solving common tasks in CouchDB if you
have an RDBMS background:

It doesn't cover your case, but I intend to add it.
