Tue, 2013-10-01 03:00
If you have to deal with a large number of documents when doing queries against a Couchbase cluster it is important to use pagination to get rows by page. You can find some information in the documentation in the chapter "Pagination", but I want to go in more details and sample code in this article.

TL;DR: Look at the Couchbase Ansible Playbook on my Github. Introduction   When I was looking for a more effective way to create my cluster I asked some sysadmins which tools I should use to do it.
