> Unless I'm really reading this wrong, I think the code [here|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/service/StorageProxy.java#L829-L843],
which comes from CASSANDRA-10674, isn't working properly.
> More precisely, I believe we can have both paired and unpaired mutations, so that both
{{if}} can be taken, but if that's the case, the 2nd write to the batchlog will basically
overwrite (remove) the batchlog write of the 1st {{if}} and I don't think that's the intention.
In practice, this means "paired" mutation won't be in the batchlog, which mean they won't
be replayed at all if they fail.
