This test covers an important aspect of Trino connectors -- metadata listing should work also while tables/views/materialized views are being created or dropped. It helped discover real problems, e.g. - in Iceberg, that's why it was created - in Kudu: trinodb#12974, - in SQL Server https://github.com/trinodb/trino/blob/8edaa86c6b43e5f5fe03bb9427d3f26439a60d15/plugin/trino-sqlserver/src/test/java/io/trino/plugin/sqlserver/BaseSqlServerConnectorTest.java#L151-L152 However, this turned out to be hard to test. The existing test is pretty complicated, takes a lot of time, has high timeout value and remains one of the more flaky tests. The test author does not know how to make it robust and perhaps does not want to remain as the author of the top flaky test in the project.
