+ Use structured logging (ex: https://www.structlog.org/en/stable/why.html)

Structured logging is just tracing but less powerful. "Context" and "binds" are just poor-man's spans. If you're going to go through the effort to redo your whole application's logging infrastructure just bite the bullet and use OpenTelemetry.

Edit: Good lord people, set the collector to never sample and use one of the many file exporters and you get completely bog standard logs but with a huge amount of work already done for you and enough context to follow complicated multi-threaded/multi-process programs without making your head spin.

There are a few concepts to understand, but instrumenting it right from the start is valuable as it grows into a bigger system. Being a cross-cutting concern, the more code that standardizes on this the more useful it will be.
