public long cas()
The CAS value is an opaque identifier which is associated with a specific state of the document on the server. It can be used during a subsequent mutation to make sure that the document has not been modified in the meantime.
If document on the server has been modified in the meantime the SDK will raise a CasMismatchException
. In
this case the caller is expected to re-do the whole "fetch-modify-update" cycle again. Please refer to the
SDK documentation for more information on CAS mismatches and subsequent retries.
