Overview

The Core module consists of three main components:

• Entity: Central management unit for modules

• Parameter: Persistent configuration data in SQLite

• Volatile: Volatile, fast data storage with Redis

Component Interaction

The three components work closely together:

1. VyraEntity initializes and orchestrates all module components

2. Parameter manages persistent configurations (slow, permanent)

3. Volatile manages volatile real-time data (fast, temporary)

Tip

Use Parameter for configuration data that should persist between restarts. Use Volatiles for real-time data and fast caching.
