Pagination solution for Salat/Cashbah

Question

I am interested in a pagination solution for documents stored in MongoDB. I use Salat/Casbah in order to work with this data. As far as I can tell, there is nothing readily available in as far as open source to paginate data using those two solutions. Is there a solution I'm currently overlooking in order to paginate data that I'm displaying in an HTTP API using those as my drivers?

Answer 1

please, be careful with pagination! In MongoDB pagination very often results in iteration over entire collection. Exactly because of this casbah doesn't have good pagination solution. You can try to use filtering instead of pagination, for example when result is ordered by field relevance, selecting results where relevance > some value

There're a lot of information about how to do efficient paging in mongodb, e.g.: MongoDB - paging

Answer 2

Despite its cheesy attempts at humor, this post on MongoDB paging is pretty good and focuses on range queries and associated techniques to paginate your data. How you actually do it depends on the amount of data and the nature of your application.
