------------------------------------
Summary: GCCompactionTest is flaky
Key: CASSANDRA-12664
URL: https://issues.apache.org/jira/browse/CASSANDRA-12664
Project: Cassandra
Issue Type: Bug
Components: Local Write-Read Paths
Reporter: Stefania
Priority: Minor
Fix For: 3.x
{{GCCompactionTest}} was introduced by CASSANDRA-7019 and appears to be flaky,
see for example
[here|https://cassci.datastax.com/view/Dev/view/sbtourist/job/sbtourist-CASSANDRA-9318-trunk-testall/lastCompletedBuild/testReport/org.apache.cassandra.cql3/GcCompactionTest/testGcCompactionStatic/].
I think it's the same root cause as CASSANDRA-12282: the tables in the test
keyspace are dropped asynchronously after each test, and this might cause
additional flush operations for all dirty tables in the keyspace. See the
[callstack|https://issues.apache.org/jira/browse/CASSANDRA-12282?focusedCommentId=15399098&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15399098]
in 12282.
A possible solution is to use KEYSPACE_PER_TEST, which is instead dropped
synchronously.
