is it possible to use REST to insert data into the bucket? What I found is you can manage the bucket, manage/use the view code by REST.
Couchbase server does not expose, today, a REST interface to insert data.
You can create your own using one of the SDK ( http://couchbase.com/develop ) or use the NGINX plugin : https://github.com/couchbaselabs/couchbase-nginx-module
Also we are currently working on a REST interface you can find the proposal here:
