Disable parallel processing for the Ordered mode for the test_storage_s3_queue/test.py::test_multiple_tables_streaming_sync_distributed test. The reason for this is that the load between the processing nodes is too uneven when s3queue_processing_threads_num != 1, e.g.: ``` $ grep res1 pytest.log 2024-08-07 07:15:58 [ 575 ] DEBUG : res1 size: 13300, res2 size: 1700, total_rows: 15000 (test.py:813, test_multiple_tables_streaming_sync_distributed) ``` In CIs environment, there are rare cases when one of the processors handles all the workload, while the other is busy-waiting, and the test fails on assert: When s3queue_processing_threads_num == 1, the workload is evenly distributed: ``` $ grep res1 pytest.log 2024-08-07 07:26:52 [ 586 ] DEBUG : res1 size: 7200, res2 size: 7800, total_rows: 15000 (test.py:813, test_multiple_tables_streaming_sync_distributed) ``` This change only fixes test flakiness. Further investigation of the Order mode parallelism is required. |
