Temporal Ruby has reached General Availability, offering Ruby developers a robust SDK for authoring durable software that aligns with Temporal's framework for writing long-running, crash-resilient code. Temporal Workflows, a core feature, ensure deterministic execution by recording actions as events, allowing resumption after interruptions. The Ruby SDK, leveraging a Rust Core to handle complex state management and asynchronous tasks, translates Ruby Workflow code into durable software without imposing gRPC dependencies. It introduces high-level constructs like Temporalio::Cancellation and Temporal::Workflow::Future to manage asynchronous workflows, employing a custom fiber scheduler to ensure deterministic execution. The SDK also incorporates TracePoint for illegal call tracing, ensuring Workflow determinism by disallowing non-deterministic operations like system time calls. Despite challenges, such as synchronizing Ruby's fiber constructs with Temporal's model, the SDK offers comprehensive tools for building reliable, scalable systems, underlined by the community's collaborative enhancements and feedback-driven improvements.
