Lifecycle

This section covers how to implement lifecycle methods that control your microservice's initialization and shutdown behavior.

Overview

Rumi microservices have a well-defined lifecycle from initialization through running to shutdown. You can hook into this lifecycle using annotations to perform setup, initialization, and cleanup tasks.

Lifecycle Phases

1. Construction - Class instantiation

2. Initialization - @AppInit methods execute

3. Running - Message processing begins

4. Shutdown - @AppShutdown methods execute

Topics

• Implementing Lifecycle Methods - Use @AppInit and @AppShutdown annotations

• Initializing the Microservice - Handle first and initial messages for state initialization
