Hasura 2.0 Engineering Overview

The Hasura GraphQL Engine version 2.0 was announced in February after six months of engineering effort across the company. This release includes significant refactoring to the core of the product and new feature additions. Some key changes include switching to a "Parse Don't Validate" approach, separating storage of Hasura's metadata from Postgres database, support for multiple Postgres backends, support for SQL Server, and support for inherited roles. Despite these changes, 2.0 remains backward compatible with previous releases after an automated metadata upgrade. The release also includes support for REST endpoints in addition to GraphQL.
