Some of the optimizations are prerequisites for a high-performance data warehouse. Sometimes Data Engineers write downstream ETLs on ingested data to optimize the data/metadata layouts to make other ETL processes cheaper and faster.

And in order to gain visibility into these logs, we need to somehow ingest and enrich this data. It is easier to tune a large Spark job for a consistent volume of data. In other words, we are able to ensure that our Spark app does not “eat” more data than it was tuned to handle. We named this library Sqooby.

The folks on the Cloud Data Engineering (CDE) team, the ones building the paved path for internal data at Netflix, graciously helped us scale it up and make adjustments, but it ended up being an involved process as we kept growing. We’ll be writing about those new features as well — stay tuned for future posts.
