Code Review
This pull request introduces parallel processing for downloading and processing Census County Business Patterns data, caches the StatVars MCF locally to optimize performance, and removes golden data validation checks. The review feedback highlights several critical improvement opportunities: streaming files directly in main.py to avoid potential Out-Of-Memory (OOM) errors during parallel execution, tracking and failing fast on sharding failures in Step 1 of shard_input_csv.sh, and ensuring proper error propagation inside the split_csv shell function.
