Should we change the used logging library?

[kwitsch]

Since there are multiple libraries for structured logging and logrus (which we currently use) falls behind in most benchmarks we should reevaluate it.

Should we change it?
If yes, to which?

[ThinkChaos]

Go now has the slog module in the standard library, probably worth a look but I've never used it personally.

I came across zap which also has an slog integration.
The comparison on there repo got me thinking...😅

I used zap, zerolog and slog in my other projects. All of them are not compatible with logrus, so each log statement must be changed. Advantage of slog: there is no need to include some dependencies and I would personalty prefer slog (I think golang team will optimize it in the future). There is also fast growing comunity with additionional projects like github.com/lmittmann/tint

Regarding benchmarks: the question is, even if logrus is slower, does it impact the overall performance of blocky? We do have very good test coverage and a lot of tests (also e2e) but no automatic benchmarking/profiling. Maybe we should do something in this direction? so we can identify potential bottlenecks and slow implementations.
