> Dtest
> cdc_test::TestCDC::test_insertion_and_commitlog_behavior_after_reaching_cdc_total_space
> always fails on an assertion.
> the assert is the final step of the test and it checks that
> pre_non_cdc_write_cdc_raw_segments == _get_cdc_raw_files(node.get_path())
> This fails 100% of the time locally, 100% of the time on circleci executed
> under pytest, and 100% of the time for the past 40 test runs on ASF Jenkins
> runs against trunk.
> This is the only test failure (excluding flaky one-off failures) remaining on
> the pytest dtest branch. I'm going to annotate the test with a skip marker
> (including a reason reference to this JIRA)... when it's fixed we should also
> remove the skip annotation from the test.
