People often say that Observability is a Data problem. Although, it sounds correct intuitively, I cannot say that I fully understood how Data engineering approaches could be applied to the Observability systems.

This article about Wide Events clarified things for me a bit. Indeed, if any event that happened in the system is just an object with some value and useful metadata, things like metrics, logs, and traces become less relevant - it's all events now!

Apparently, this is how Observability is done in Meta, according to the author, and apparently people in Meta like it. I never worked for Meta, I don't know what they really use there and if it's better than the tools available to us mere mortals.

However, this is an interesting concept, and it would be wonderful to see similar projects that are not internal to the Big Tech companies.
