"""
Event publishing/subscribing abstraction layer.

Supports:
- Redis Pub/Sub (default, simple)
- Redis Streams (with consumer groups, persistence)
- Kafka (future, for high-throughput)

Usage:
    from shared.events import get_publisher, get_subscriber

    # Publishing
    async with get_publisher() as pub:
        await pub.publish("metrics.raw", {"machine_id": "m1", ...})

    # Subscribing
    async with get_subscriber(["metrics.raw", "alerts.*"]) as sub:
        async for topic, message in sub.consume():
            process(topic, message)
