Structured Logging for the Standard Library - Jonathan Amsterdam

Improve logging performance in Go with Structured Logging: a fast, efficient, and simple solution aimed at making the standard library's default logger.

Key takeaways

Structured logging is proposed for the Go standard library to improve logging performance.
Memory allocation is a significant obstacle to efficient logging.
Logging should be done simply, with no unnecessary complexity.
The proposed Slog library aims to provide a fast and efficient way to log.
Zap, a structured logging library, is used as a reference point.
The Slog logger uses a simple and static approach to logging.
The logger creates a record that can be used to produce log lines.
The record includes the time, level, and message.
Handlers are used to produce log lines from records.
A pool of handlers is used to avoid memory allocation.
The Slog logger is used as a replacement for the standard Go log package.
The goal is to make the logger easy to use and safe.
The default logger is set to the Slog logger.
The Slog logger is designed to be fast and efficient.
The logger creates a record and then calls the handle method.
The handle method produces the log line.
The Slog logger is tested and compared to Zap.
The results show that Slog is faster than Zap.
The Slog logger is included in the Go standard library.
