     *   `_DATASET_NAME`: The name of the BigQuery dataset to store results (e.g., `gcsfs_benchmarks`).
+    *   `_INFRA_PREFIX`: The prefix used for resources in the benchmarks run (e.g., `gcsfs-perf`). Must match the one used in the run trigger.
 *   **Trigger Event**: This trigger is typically scheduled to run after the benchmarks pipeline completes, or triggered manually.
