This table and query_job might not actually exist / refer to an older object since to_pandas() will likely end up in the "jobless" API path.

[shobsi]

I think this code is testing that the result of a BigFrames operation are stored in that location itself, which has value in asserting the location behavior, especially with regional endpoints. Rather than deleting, can we not do one of the following:

1. Force a query job via allow_large_results=True in the Session creation in all tests
2. Move this test code to a special test which enforces allow_large_results=True

[tswast]

I don't think this would verify the location though. You'd have to check that the dataset is in the correct location. Otherwise, this would read from whereever the table is.

[tswast]

I have forced a job and validate the location of the stored results in 15fa728.

@Genesis929 @shobsi Please review.

[tswast]

New e2e failure is FAILED tests/system/small/ml/test_multimodal_llm.py::test_multimodal_embedding_generator_predict_default_params_success which is unrelated.

New notebook failures is notebooks/generative_ai/bq_dataframes_llm_kmeans.ipynb, which is unrelated.

@Genesis929 please review again. I think the setting to dismiss stale reviews has been turned on for security reasons.
