Andres de la Peña commented on CASSANDRA-16567:
-----------------------------------------------
I think that the failure happens because the truncation of a table doesn't stop
the asynchronous builders of its materialized views. As a result, it's possible
that, after truncating a table, still running MV builders insert pre-truncate
rows into the MV. The proposed PR simply makes sure to stop any ongoing MV
builds when a table is truncated, [this
way|https://github.com/apache/cassandra/pull/967/commits/3e3a6fd699c819c3642a810074f5fcbe174cda64].
Also, the PR adds [a simple
test|https://github.com/apache/cassandra/pull/967/commits/c5eea8d0311c9aba8e223072cd600a87c86dec6d]
reproducing the problematic scenario more consistently than
{{testCompoundPartitionKey}}.
Also, although it's not related to the failure, I've noticed that {{ViewTest}}
still uses {{ProtocolVersion.V4}} instead of the current one. I think this is
not intentional so I've also
[changed|https://github.com/apache/cassandra/pull/967/commits/f30007a990b16e5f9c1c151051c1a21ccb689030]
the test to use {{CQLTester.getDefaultVersion}} instead.
