EdgeDB 1.0 Alpha 5 "Luhman" introduces several enhancements aimed at improving database administration and user experience, including simplified credential management with named instances that store credentials like SSH and AWS CLI, allowing users to connect to an instance simply by its name. It also introduces the "upsert" operation via the INSERT ... UNLESS CONFLICT ... ELSE syntax to streamline inserting or updating data, along with type-level constraints that enforce data integrity by allowing constraints on multiple properties. Enhancements in JSON casting now support arrays and tuples, while the JavaScript client API gains transaction block capabilities to manage complex database interactions with error handling. GraphQL support is improved with multiple mutations in a single query, and sorting on complex paths, alongside the introduction of stored migrations for a more robust migration workflow. These updates underscore EdgeDB's goal to make database operations more efficient and user-friendly, with a focus on composability and regularity in query language, as well as enhanced interoperability through REST and GraphQL.
