StartupStep class abstract

Step recording metrics about a particular phase or action happening during the ApplicationStartup.

A StartupStep represents a logical segment of application startup. It supports tagging, nesting (via parent-child relationships), and can be timed or analyzed for startup diagnostics.

Lifecycle:

  1. The step is created via ApplicationStartup.start and assigned a unique id.
  2. One or more tags may be attached using tag or tagWithSupplier.
  3. The end method is called to finalize the step.

Implementations can use this for startup profiling, telemetry, or logging.

Example:

final step = applicationStartup.start('context.refresh');
step.tag('pod.name', 'dataSource');
step.end();
