Limitation on number of databases? (see thread)

Question: A user was wondering if CouchDB was imposing any limit on the number of databases which a single instance can serve (and replicate).

Answer: There are two limits:

Operation system limit on file descriptions user allowed to manage (see uliimit). CouchDB inner limitation. See the CouchDB Docs for details.

Configuring these options right allows you to serve thousands active

databases without any problem.

CouchDB to csv file (see thread)

Question: a user is working on a script in Java to convert a whole CouchDB into a csv file and wants to know about the easiest way to do that.

Approaches:

using `/{db}/_all_docs?include_docs=true` (see docs)

Couch has an HTTP API, so you have to pull the right URL in Java (i.e. open a java.net.Connection to the right URL). You can try the URL in the browser before to check whether all the right data is there. So, you can point your browser to http://{server}:{port}/{db}/_all_docs?include_docs=true and check if you have all info in it. Then you can use something like (new java.net.URL(“http://{server}:{port}/{db}/_all_docs?include_docs=true”).openConnection()) to grab the URL connection and work from there. Using something like this is certainly useful

when moving forward.
