FAQ
Why is minitrace so fast?
There are some articles posted by the maintainer of minitrace:
- The Design of A High-performance Tracing Library in Rust (Chinese)
- How We Trace a KV Database with Less than 5% Performance Impact
Why / What's the difference compared to 'X'?
Most tracing libraries aims to provide more features, while minitrace always prioritize performance. Usually minitrace only provides basic and common tracing features.
Will you support OpenTelemetry feature 'X'?
Minitrace is focused on high performance tracing only. You can open an issue for the missing tracing features you want to have.
Note that we always prioritize performance over features, so that not all tracing feature requests may be accepted.
What's the status of this library?
API Unstable: The API is not stabilized yet, may be changed in the future.
Code base Tested: Minitrace has been tested with high coverage. However, applications utilizing minitrace have not been widely deployed, so that minitrace is currently NOT regarded as battle-tested.
