At first glance, ingesting data into a data lake may seem like a one-step process — you simply add files to an object store.

The truth is, once you’ve written it to the lake, in a sense, it’s already too late.What we propose and will cover in this talk, is a new strategy for data lake ingestion. One where new data can be added in isolation, then tested and validated, before “going live” in a production table. Finally, we’ll show how Data as Code tools like lakeFS and Nessie enable this ingestion paradigm in a seamless way.
