How can we update documents transactionally in couchbase?

I have a use case in which there are three documents and I want to update them transactionally i.e. if any of them fails then other too should not get updated in the database. I was looking for an option but didn't find one in JavaSDK. So is there any way in which I can perform this operation transactionally. I am using the CAS value for handling the concurrency. Please provide me a way to handle this operation concurrently.

Couchbase Version: 4.0 Java SDK: 2.1.6

Any help is appreciated.!

Couchbase now supports full ACID distribution transactions in the beta release of Couchbase Server 6.5. Please see this blog post for more details and links to the documentation.

Couchbase is a NoSQL database, where there is a tradeoff between ACID properties of traditional RDBMS and performance and scalability.

The only atomicity that couchbase can enforce is at the level of a single document.

There could be writings around the web on how to implement a transaction system with Couchbase, but that is clearly not something supported off-the-shelf, by design. It is a very complicated endeavour that I wouldn't recommend.

Try to model your documents differently first, so that the mutation can occur on a single document (where CAS could then be used).
