In computer databases, the Check-And-Set value is the ID of the most recent version of a NoSQL data document. If you have multiple versions of a document, each version will have its own CAS value.

The CAS value for a given document while you are getting the document may be useful if you want to update it, but want to do so while avoiding conflict with another document change.
I'm not sure if Bob updated the document, so I'm just going to use a different CAS.
