# Why We Moved to Event Queues

- Requests no longer wait on slow consumers
- Retries happen without user involvement
- Each consumer scales on its own

# Throughput Before and After

| Metric               |   Before |   After |
|----------------------|----------|---------|
| Peak jobs per minute |     1200 |    4800 |
| Median latency (ms)  |      850 |     210 |
| Failed jobs per day  |       37 |       4 |

# What Still Needs Work

- Dead-letter handling is manual
- Consumer lag alerts are too noisy
- Replay tooling needs access controls
