Data sources
Stories about reading and writing data: the Data Source API, V1 vs V2, and how formats plug in.
Planned stories:
- How a read becomes partitions and tasks (scan, partition discovery)
- V1 vs V2 data source API: why two APIs and when each is used
- File formats (Parquet, ORC, etc.) and the role of the format in the plan
Stories will be added here gradually.
