[jira] [Commented] (CASSANDRA-7163) dtests should reuse existing clusters where possible

["Russ Hatch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-7163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13990059#comment-13990059 ] 

Russ Hatch commented on CASSANDRA-7163:
---------------------------------------

One possibility here might be some simple helpers in the Tester class to track a keyspace name on a per-test basis. A uuid would be great for this, and would prevent table name collisions. Then the tests can just ask for a keyspace when needed (and not really care what the actual value is).

> Many dtests don't require special setup, specifically the cql tests. We can reuse the clusters we setup across multiple tests to save time.
> Suggestion: only share clusters across a single test suite, and don't share the cluster by default, turn it on per-class. If we share them more broadly than that we may get into weird states because some tests definitely do mess with the cluster setup.
