Transactions in NoSQL?

Question

I\'m looking into NoSQL for scaling alternatives to a database. What do I do if I want transaction-based things that are sensitive to these kind of things?

Answer 1

You can implement optimistic transactions on top of NoSQL solution if it supports compare-and-set. I wrote an example and some explanation on a GitHub page how to do it in MongoDB, but you can repeat it in any suitable NoSQL solution.
