Hasura introduces a GraphQL-based data virtualization cloud

GraphQL, which has nothing to do with graph databases but has everything to do with JSON query, was a technology originated at Facebook to simplify getting access to data. Now, Hasura, a two-year old company, is building a data virtualization tool around it and last week introduced a cloud service. At the core of Hasura's offerings is its own implementation of a GraphQL query engine that it has open sourced. Currently designed to work against PostgreSQL-compatible databases, the engine scans the metadata of specified tables on the target, builds a GraphQL endpoint, represents the data in JSON format, and automatically generates a selection of possible queries. Atop its GraphQL query engine, the original Hasura enterprise on-premises offering includes adapters for PostgreSQL databases; other relational targets are planned in the future.
