AWS Lambda durable functions arrive for Go with local testing and a resume-safety linter

AWS has made the Lambda Durable Execution SDK for Go generally available, bringing Lambda durable functions to Go developers. Durable functions extend Lambda's event-driven model with automatic checkpointing, so a workflow can pause for up to a year while it waits on an external event and then resume where it left off. The SDK provides steps for progress tracking, callbacks for human- and agent-in-the-loop approvals, durable invocation for reliable function chaining, and waits for efficient suspension. It installs with go get and deploys as a single static binary on the provided.al2023 runtime, like any other Go function. The practical extras matter most: a durabletest package runs complete workflows locally with no network or AWS credentials, and a durablelint analyzer flags code that could break a workflow when it resumes. Typical fits include infrastructure automation, deployment rollouts with approval gates, and pipelines that call AI models and pause for human review.
