Temporal is an open source, distributed, and scalable workflow orchestration engine that allows developers to code at a higher level of abstraction, eliminating the need to reimplement distributed systems patterns. It provides reliability, fault tolerance, and scalability out of the box, enabling developers to focus on coding business logic. Temporal captures the progress of a workflow execution in a log called the history, allowing it to rehydrate the workflow in case of a crash, without requiring special handling in application code. This technology is particularly useful for managing long-running workflows, such as file updates and background checks, which can take hours or days to complete. PlanetScale is a database that complements Temporal by providing operational simplicity and scalability, allowing developers to deploy Temporal clusters quickly and easily.
