Temporal 102: Exploring Durable Execution with Java is a new self-paced online training course that focuses on best practices and key concepts for deploying Temporal applications to production. Unlike Temporal 101, which covers the basics of building and running a basic Temporal application, this course emphasizes testing, debugging, and deployment strategies. The Java version of Temporal 102 is slightly different from its Go counterpart, with some content reorganized or removed. Future versions in TypeScript and Python are expected by the end of 2023. A separate course on Versioning will be released soon.
