In this livestream, Chad Retz (Temporal SDK maintainer, 4+ years at Temporal) digs into the open source code that powers your workflows.

We go beyond the surface and explore:

• Why Temporal is fully MIT licensed (and why that matters)
• The difference between the Temporal Server and the SDKs
• How the Python SDK turns your code into durable, replayable workflows
• What really happens when you call execute_workflow
• How workers poll, replay history, and deterministically execute your code
• Interceptors, activations, commands, and the Rust core
• Error handling, retries, and gRPC under the hood
