replaceAliveHost) that are not remotely touched by this work.
> Support atomic addition and append for LWTs

> Key: CASSANDRA-16936
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16936
> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Lightweight Transactions
> Reporter: Benedict Elliott Smith
> Assignee: Benedict Elliott Smith
> Priority: Normal
> Fix For: 4.x
>
>
> 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.
