Can this skill help with database sizing?

Yes, it provides specific CPU, memory, storage, and IOPS recommendations for PostgreSQL based on total workflow volume and retention requirements.

Why are history shards so important in Temporal?

History shards determine the maximum workflow parallelism. Because they cannot be changed after a cluster is created, getting the initial count right is critical for long-term scalability.

How do I know when to scale my cluster services?

The skill identifies key metrics like sustained CPU utilization over 70%, memory over 80%, or p99 request latency as triggers for horizontal or vertical scaling.

Does it provide deployment configurations?

Yes, it includes YAML templates for small (dev/test), medium (production start), and large (high volume) cluster profiles including resource requests and limits.

Cloud Infrastructure

Provides expert guidance and capacity planning for Temporal clusters, focusing on shard allocation and resource optimization.

The Temporal Cluster Sizing skill empowers developers and SREs to accurately architect and scale Temporal orchestration engines by providing data-driven infrastructure recommendations. It offers precise calculations for history shards—a critical, immutable configuration—as well as replica counts and resource requirements for Frontend, History, and Matching services. By leveraging this skill within Claude Code, users can avoid common pitfalls like undersized persistence layers or insufficient shard counts, ensuring their workflow engine handles production loads ranging from 10,000 to over 2 million concurrent workflows with high availability.
