Andres de la Peña commented on CASSANDRA-17213:
-----------------------------------------------
Yes, right, we should also split the tests in 3.11. The tests are quite
different in that branch and their names are quite long, I hope that the new
names that I have used for the classes make sense:
||PR||CI pre-fix||CI post-fix||
|[3.11|https://github.com/apache/cassandra/pull/1629]|[j8|https://app.circleci.com/pipelines/github/adelapena/cassandra/1558/workflows/34021f5a-1543-4b8a-b67c-801b7987d1ba]|[j8|https://app.circleci.com/pipelines/github/adelapena/cassandra/1561/workflows/bb9096e7-ebc4-46ee-90eb-53dd8d42a4c0]|
As it happened with 4.0, [the tests
OOM|https://app.circleci.com/pipelines/github/adelapena/cassandra/1558/workflows/34021f5a-1543-4b8a-b67c-801b7987d1ba]
quite easily without splitting them., and once we get rid of the OOMs [a new
type of
failure|https://app.circleci.com/pipelines/github/adelapena/cassandra/1561/workflows/bb9096e7-ebc4-46ee-90eb-53dd8d42a4c0]
gets exposed. To make sure that that masked failure isn't introduced by a
mistake while splitting, I have run
{{CompactStorage2to3UpgradeTest#testDropCompactWithClusteringAndValueColumnWithDeletesAndWrites}}
unpatched and in isolation. [That
experiment|https://app.circleci.com/pipelines/github/adelapena/cassandra/1562/workflows/77329cd5-3d3d-4a8f-beb5-8f64818df0f5]
shows that the test is indeed flaky independently of the OOM that we are
trying to fix here.
