[jira] [Commented] (CASSANDRA-15579) 4.0 quality testing: Distributed Read/Write Path: Coordination, Replication, and Read Repair

["Andres de la Peña (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-15579?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17148804#comment-17148804 ] 

Andres de la Peña commented on CASSANDRA-15579:
-----------------------------------------------

I'm keen to start work on unblocking this, but I don't know what should be the scope of this ticket or where to start.

We have a fair number of specific dtests around this area, at least:
 * [consistency_test|https://github.com/apache/cassandra-dtest/blob/master/consistency_test.py]
 * [replication_test|https://github.com/apache/cassandra-dtest/blob/master/replication_test.py]
 * [read_repair_test|https://github.com/apache/cassandra-dtest/blob/master/read_repair_test.py]
 * [replica_side_filtering_test|https://github.com/apache/cassandra-dtest/blob/master/replica_side_filtering_test.py]

We also have some related in-jvm distributed tests, and things like coordination are also implicitly included in some other tests.

[~bdeggleston] Do we have a more specific list of what things do need testing, or what cases are missed in the existing tests? Have we identified especially suspicious components or use cases that can be prioritized?

> Testing in this area focuses on non-node-local aspects of the read-write path: coordination, replication, read repair, etc.
