ROAPI automatically spins up read-only REST, GraphQL, SQL, and FlightSQL query APIs over static or slowly moving datasets without writing any code. It is built on Apache Arrow and Datafusion, loading data from files, S3, Delta Lake, or databases with automatic schema inference.

Use cases

• expose a csv file as a rest api
• query parquet files on s3 with sql
• spin up a graphql api for a dataset without writing code
• serve a json file as a queryable table
• join data from multiple sources via one api
• quickly share analytics data with a query endpoint

When to choose

• you need read-only query APIs over static or slowly changing datasets with zero code
• you want SQL, GraphQL, and REST frontends over the same data
• you need automatic schema inference across CSV, Parquet, JSON, and databases

When to avoid

• you need write support or transactional updates
• you need a full production database with user management and fine-grained auth
• your datasets change rapidly and require real-time consistency
