Declarative config 0.4 #7064

jack-berg · 2025-02-03T20:11:06Z

v0.4.0 is a big release for declarative config, full of a large number of breaking changes, enhancements, and fixes as the result of applying additional scrutiny as we approach stability.

We anticipate limited churn going forward.

wait these can't be combined/composed? 😢

using the toString() for testing seems error prone and fragile, but it's what we have right now....and anything else would understandably be quite difficult.

Really surprised at the sheer volume of code required to support configuration! I wonder if we'll have this exercise with every version, or if it's mostly that this one was particularly beefy....

Anyway, thanks for taking this on!

Really surprised at the sheer volume of code required to support configuration! I wonder if we'll have this exercise with every version, or if it's mostly that this one was particularly beefy....

Yeah I'm a bit surprised the volume too. I think the volume / complexity of config mostly reflects the essential complexity of what otel specified requirements for SDKs up to this point. I.e. it can probably be expressed a little more concisely / simply, but not too much without being opinionated and chopping off concepts.

If we're as close to stabilizing declarative config as I think we are, this PR should be significantly larger than future PRs. The things that make for big PRs are: 1. large refactoring of the declarative config schema 2. large introduction of new declarative config schema. Both of those should be greatly reduced going forward.
