Faster Throughput & Lower Latency with Temporal Cloud

This post details Temporal Cloud's custom persistence layer, focusing on three key architectural pillars: better sharding for dynamic resizing and handling traffic spikes, a write-ahead log (WAL) to aggregate writes and improve recovery, and tiered storage to move completed Workflow Event Histories to object storage, reducing database load and improving performance. These improvements result in higher scalability and lower latency compared to self-hosted clusters.
