-------------------------------------------
[~jasonstack] - any movement on this? Do we have a backlog of things we've
identified we want to work on or suspect needs TLC we can enumerate here?
> 4.0 quality testing: Materialized View
> --------------------------------------
>
> Key: CASSANDRA-15921
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15921
> Project: Cassandra
> Issue Type: Task
> Components: Feature/Materialized Views
> Reporter: Zhao Yang
> Assignee: Zhao Yang
> Priority: Normal
> Fix For: 4.x
>
> Attachments: C40_MV.png

> The main purpose of this ticket to get a better understanding about 4.0 MV
> status as a guideline for future improvements. I don't think it should block
> 4.0 release since it's already marked as experimental.
> Main areas to test:
> * Write perf: We expect to see [10% write throughput drop per MV
> added|https://www.datastax.com/blog/2016/05/materialized-view-performance-cassandra-3x].
> ** Attached C40_MV.png is alpha-4, 5-node, rf3 MV write tests: with 1 mv,
> throughput dropped 50%
> * Read perf: identical to normal table
> * Bootstrap/Decommision: no write-path required since CASSANDRA-13065
> * Repair: write path required
> * Chaos monkey: take down coordinator/base-replica/view-replica during
> read/write/token-movement and verify data consistency (may need a tool)
> * Hint Replay: able to throttle if table has MV - CASSANDRA-13810
> * Schema race: create/drop - CASSANDRA-15845/CASSANDRA-15918
