Is it possible to gather data from various databases into another?
Imagine an architecture in which there is a database per group
discussion.
Each user has their own private database into which data is pulled out
all the various discussion databases that they have access to.
Is there a mechanism in Couchdb to pull data from various databases
into another one?
thanks

Well you can do anything really - just be careful so that you don't cause
too many replication conflicts and be careful with your replication filters.

And you can have a database replicate from two different databases or more.
Right?

You are actually missing something. Replication is one way, both source and destination can be either local or remote and you can use arbitrary databases as source and destination.

The document you linked to suggests that replication is one to one,
from one database in one location to *the same* database in a
different location.
Unless I'm missing something I can't see how replication allows data
to come from multiple different databases into another database.
Any other ideas?
Thanks

Requesting explanation of terms in CouchOne announcement
Posted by "Andrew Stuart (SuperCoders)" <an...@supercoders.com.au>.
Hello
The CouchOne announcement http://www.membase.com/merger-technology-vision
refers to the following terms but there's not much to explain them:
** user code execution across database nodes with scatter-gather support
** multi point triggers
Can someone refer me to explanations of these terms please?
The announcement also refers to indexing and query support - does this
mean in the future CouchDB will include more traditional types of
field oriented indexes?
Thanks
