Building Hasura: Instant realtime, high-performance GraphQL on Postgres
Hasura is an open-source engine that gives developers instant GraphQL on a new or existing Postgres database. This GraphQL server can handle upwards of a 1000 requests per second, even for deeply nested queries, with an extremely low resource footprint of 50-60MB of RAM.
Hasura does this by taking a unique approach of compiling GraphQL queries instead of resolving them. This results in huge-performance benefits.
In this talk, I’ll touch upon the design of the system, the structure of the GraphQL query and Postgres optimizations that can be leveraged and share other engineering learnings as we built Hasura.
