I built the battle pass system for Hytale. It tracked player progress and rewards. I focused on low latency first. This was the wrong move.
I used Redis and PostgreSQL. The system failed under high traffic. Connection timeouts happened often. I tried Apache Kafka. It added too much complexity.
I changed my strategy. I prioritized consistency and fairness. I used Apache Cassandra and Apache ZooKeeper. I added Hazelcast for caching.
The results:
- Response time dropped from 500ms to 50ms.
- Error rate dropped from 10% to 0.1%.
- Peak load hit 10,000 requests per second.
- Availability rose from 95% to 99.99%.
Pick your metrics carefully. Consistency often beats speed. Build a strong caching layer. Use Prometheus and Grafana to find bottlenecks.
