Project Every Record Counts: Data Engineering for Backend Engineers
Part 15: "Getting Data In" — Batch Ingestion: Files, APIs and Databases
A supplier renames one column and Larkspur's scorecard says it delivered nothing for six weeks. Season 2 opens with ingestion as a contract with systems you don't control: full vs incremental extraction, the three traps of a high-water mark, landing zones and an immutable raw zone, pagination, rate limits and retries, schema drift and load metadata, built with dlt into Iceberg through Polaris.
