Fan-Out Pattern for Multiple Destinations

Send data to multiple destinations simultaneously without duplication overhead.

The Problem

Edge processing needs to send the same data to multiple destinations:

• Kafka for real-time streaming, S3 for archive, Elasticsearch for search
• Each destination has different requirements and failure modes
• One destination failure shouldn't block others

The Solution

Learn 5 fan-out routing techniques:

1. Concurrent Distribution - Parallel delivery with broker output and fan_out pattern
2. Independent Retry Logic - Per-destination retry and backoff configuration
3. Batching Optimization - Destination-specific batching and compression tuning
4. Failure Isolation - Independent error handling and circuit breakers per destination
5. Local Fallback Chains - Local buffering with automatic cloud sync during outages
