[jira] [Created] (CASSANDRA-16936) Support atomic addition and append for LWTs

Benedict Elliott Smith created CASSANDRA-16936:
--------------------------------------------------

             Summary: Support atomic addition and append for LWTs
                 Key: CASSANDRA-16936
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16936
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Benedict Elliott Smith


To support CEP-10 we require some atomic functionality that modifies the state of a register as part of the transaction. Specifically, we require at least the ability to append a string to another string. Since this is more widely useful, at the same time we also support addition on numeric fields so that users may maintain precise counters using Paxos, should they wish.
