Paulo Motta commented on CASSANDRA-13069:
-----------------------------------------
sorry for the delay, got sucked into other things but I am halfway through a
patch so will submit this or next week.
> Local batchlog for MV may not be correctly written on node movements

> Key: CASSANDRA-13069
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13069
> Project: Cassandra
> Issue Type: Bug
> Components: Materialized Views
> Reporter: Sylvain Lebresne
> Assignee: Paulo Motta

> 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.
