    Flogger

    Flogger

    A Fluent Logging API for Java

    Flogger is a structured logging API for Java that decouples how you log from where logs ultimately go, making it easy to change backends without rewriting application code. Instead of building messages eagerly, it uses lazy parameter evaluation so expensive string building only happens when a log statement is actually emitted. The API encourages structured key–value context and fine-grained rate limiting, which helps keep logs informative without flooding systems during high-traffic or error storms. ...
