-------------------------------------------
Summary: 4.0 Quality: Coordination & Replication Fuzz Testing
Key: CASSANDRA-16262
URL: https://issues.apache.org/jira/browse/CASSANDRA-16262
Project: Cassandra
Issue Type: Task
Components: Test/fuzz
Reporter: Caleb Rackliffe
CASSANDRA-16180, CASSANDRA-16181, and CASSANDRA-15977 have largely focused on
auditing the existing tests around coordination, replication, and read-repair,
respectively. We've expanded existing test cases, added coverage around
components that we've refactored along the way, and added in-JVM dtest upgrade
tests where possible.
What remains is verifying the distributed read and write paths in the face of
common operational events, namely node restarts, bootstrapping, and
decommission. If we can find a way to simulate these events,
[Harry|https://github.com/apache/cassandra-harry] seems like a good candidate
to host the verification logic itself.
To keep things simple initially, I would propose that we start by testing
simple read-only and write-only workloads (the former without read repair).
