How can we update documents transactionally in couchbase?
<p>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.</p>

<p>Couchbase Version: 4.0 
Java SDK: 2.1.6</p>

<p>Any help is appreciated.!</p>
