Hasura's GraphQL engine compiles GraphQL queries into optimal SQL queries and avoids the (n + 1) queries pitfall. It also exploits multiple cores and can scale vertically and horizontally.

If each user makes an API call every seconds,

a DigitalOcean -  droplet running Hasura can support 3200 active users.

95th percentile under 15ms, for a select query fetching one nested node.
Data Modelling

Create relationships between tables, or between tables and views.

Derived Data

Create aggregations and joins with views to query on "derived" data.

Model "trees"

Make self-referencing relationships for tree-like data like comments.

Schemaless data

Store schemaless data in JSON columns.

How it works
GraphQL Architecture
How do I import my existing database?
If you have a Postgres database, all you need to do is export with pg_dump and import into Hasura's postgres instance with psql. Read the docs here. If you have a different database, you'll have to convert it to postgres first using tools like these.
Can I use my existing Postgres database hosted elsewhere?
The Hasura platform comes with its own Postgres instance and we're adding support for using an external postgres database directly. If you're on the "Pro pricing tier", you can get in touch with us and we'll see if we can figure it out for you!
