Higher throughput and lower latency: Temporal Cloud’s custom persistence layer

Temporal Cloud, a managed service for Temporal, offers better performance and lower latency compared to self-hosted clusters due to effective management and scaling by its team. The custom persistence layer of Temporal Cloud helps handle high throughput with more stable request latencies. This architecture is designed to support multiple tenants sharing the same compute and persistence layer, ensuring extra capacity for all customers during traffic spikes while addressing the noisy neighbor problem. Key features of this custom persistence solution include better sharding, a write-ahead log, and tiered storage of Workflow Event History. These enhancements result in higher scalability and lower latency for Temporal Cloud users.
