The parquet schemas have fallen out of favor, only updates to the JSON Schemas will show up in changes to the BigQuery tables.

Thanks! Are you who I should be specifically tagging for review on these kinds of things?

The parquet schemas have fallen out of favor, only updates to the JSON Schemas will show up in changes to the BigQuery tables.

Can the readme be updated to reflect that? As someone who only interacts with this stuff occasionally, it's difficult to keep up with all the changes that are always happening, and a little bit of updated documentation would go a long way.

In general, you should be able to request review and get a deploy from someone on the Data Platform team. I'm familiar with the repository, for feel free to tag me if there isn't someone else who has more context.

Can the readme be updated to reflect that?

Yes, it can. The ingestion pipeline has changed a bit during our GCP migration, leading to a drift in the documentation. The new process of modifying the schema is simpler though, once documented.
