Currently, the Couchbase Python client doesn’t implement getMulti() method yet. How can I retrive or write multiple document in bulk?
As you have noticed it is not yet implemented, so to you have to loop on the key and do simple get.
The task is created in the project :http://www.couchbase.com/issues/browse/PYCBC-49
Community and Team will work more on the Python SDK now that Couchbase 2.0 is out.
In addition to my previous comment I invite you to look at this blog post explaining our work around the Python SDK:
