Code Review
This pull request introduces sharding for the PM2.5 county pollution data to split the output into four parts, updating the manifest, tests, and template MCF files accordingly. It also refactors the file downloader to stream content in chunks to reduce memory usage, and increases resource limits in the manifest. The review feedback highlights a critical bug in the sharding logic within parse_air_quality.py that can lead to an infinite loop on the final shard and cause missing files for empty shards, providing a robust code suggestion to resolve these issues.
- Partition parse_air_quality.py for CDC_PM25County, CDC_OzoneCounty, and Census Tract datasets into discrete 5-year shards to prevent OOM/disk exhaustion. - Scale resource limits in manifest.json (up to 32 CPUs, 512GB RAM, 2TB disk) to support high-density daily time-series generation (1.064B observations). - Add streaming download in download_files.py with 16MB chunks to prevent memory spikes. - Update TMCF template files and test suite with sharded fixtures. - Add validation_config.json with deleted records and lint checks.

Findings
No actionable P0, P1, or P2 blocking findings.
Positive findings
download_files.py:40- Streamed chunked downloads ✓- Finding: Good - Replaced
response.contentin-memory buffering withrequests.get(url, stream=True)and 16MB chunk iterations, preventing high-memory spikes during multi-gigabyte archive retrieval while preserving retry decorators.
- Finding: Good - Replaced
manifest.json:18- Scaled compute & storage limits ✓- Finding: Good - Upgraded resource allocations to 32 vCPUs, 512 GiB RAM, and 2TB disk for Census Tract imports (500GB disk for County imports), preventing out-of-memory and disk exhaustion failures on high-volume datasets.
parse_air_quality.py:129- Balanced dataset sharding & defensive header creation ✓- Finding: Good - Calculates exact row-balanced partition sizes upfront, initializes output CSV headers across all partition shards on the first chunk to guarantee valid files even for edge cases, and uncaps the terminal shard to prevent row loss.
parse_air_quality_test.py:108- Multi-shard test verification & automated teardown ✓- Finding: Good - Added parameterized assertions for all generated partition shards (
PM25county_[0-3].csv) with concise test fixtures (< 1 KB each) and automatedshutil.rmtreeteardown to keep working trees clean.
- Finding: Good - Added parameterized assertions for all generated partition shards (

DO we really need 4 different tmcf files ? Cant we use single tmcf file for all sharded files?
Contributor

While a single tmcf file is possible, keeping them separate simplifies validation and maintains a 1-to-1 mapping; however, I can certainly merge them into one if that is preferred.

Following Rohit’s recommendation, the job is failing because the "differ" exceeds 100 GB, so it needs to be executed manually; I previously attempted it without this step and encountered the same configuration failure.

Verification Details:
- Built with latest commit
aaf3f00d. - Includes Socrata count query exponential backoff retries.
- Includes Census Tract chunked streaming (
chunksize=500_000) to prevent memory spikes. - Includes validation configs for both County and Census Tracts.
- Cloud Batch regions distributed across 4 distinct regions to eliminate quota bottlenecks.
