How (Not) to Build Datasets and Consume Data at Your Company

March 3rd, 2020 by George Roldugin

Two years ago, if an engineering team at SoundCloud needed data produced by another team, in many cases, that team would have had to start by building a dataset from the raw data. That meant there was no standard way to structure data into a dataset, there were errors in understanding and interpreting raw data, and there was no reuse of datasets across teams. Ownership of datasets was with the teams consuming data, even when the data itself was owned and best understood by someone else.

By agreeing on an ownership strategy, a common shape for datasets, and standard tooling, SoundCloud was able to streamline these problems away. Now the data and datasets are provided by those who know best about their data, along with the help of tooling built by those who know best about building tools. Read on to learn what datasets look like at SoundCloud and how they are built.

The Power of Types for Errors

January 20th, 2020 by Danny Preussler

Limiting the number of primitives we use in our code in favor of using custom types instead is an easy win. In this way, we as developers will not only reduce the possibility of bugs by using the compiler, but we will also achieve more readable and self-documented types.
