Code Review

This pull request adds an end-to-end integration test (test_alloydb_vector_search_benchmark) for the AlloyDB vector search benchmark notebook, utilizing scaled-down parameters to ensure fast execution in CI. The review feedback points out a mismatch in the replacement string for ef_values, which would prevent the intended replacement from executing and potentially cause CI timeouts or OOMs. A code suggestion is provided to correct the list of values to match the notebook.
