merlimat opened a new pull request, #25545: URL: https://github.com/apache/pulsar/pull/25545
### Motivation When the broker starts, the `Messaging service is ready` log entry attaches the entire `ServiceConfiguration` object. With hundreds of configuration fields, this produces pages of output on every startup — almost all of it matching the built-in defaults and adding noise without any diagnostic value. ### Modifications - Added `PulsarConfigurationLoader#runtimeConfigurationOverrides(PulsarConfiguration)` that returns the subset of `@FieldContext`-annotated fields whose current value differs from a freshly-instantiated defaults instance of the same class. Extra entries in `PulsarConfiguration#getProperties()` (not backed by declared fields) are also included. - Updated the `Messaging service is ready` log in `PulsarService` to attach `configOverrides` (the diff map) instead of the full `config` object. ### Verifying this change This change added tests and can be verified as follows: - Added `PulsarConfigurationLoaderTest#testRuntimeConfigurationOverrides` covering overrides of `String`, `int`, `long`, `boolean`, `double`, enum, `Optional<Integer>`, and `Set<String>` fields, an extra non-declared `Properties` entry, a no-op default assignment (must not appear), and the empty-overrides case for a fresh configuration. ### Does this pull request potentially affect one of the following parts: - [ ] Dependencies (add or upgrade a dependency) - [ ] The public API - [ ] The schema - [ ] The default values of configurations - [ ] The threading model - [ ] The binary protocol - [ ] The REST endpoints - [ ] The admin CLI options - [ ] The metrics - [ ] Anything that affects deployment -- This is an automated message from the Apache Git Service.
