Fast analytical queries

Built in Rust with Apache Arrow and DataFusion, Beacon is designed for efficient filtering, projection, and retrieval across large scientific datasets.

🧩

Works with existing formats

Query NetCDF, Zarr, Parquet, CSV, ODV, Arrow, TIFF, Atlas and BBF datasets without converting everything into a proprietary warehouse.

🧱

Create tables and views

Define external tables over existing files, create reusable SQL views, and expose curated datasets to downstream users and applications.

🔌

SQL and JSON APIs

Serve scientific data through queryable SQL and JSON interfaces for portals, dashboards, notebooks, services, and data products.

🧭

Query from your favorite tools

Use Arrow Flight SQL to connect Beacon to JDBC-compatible SQL clients such as DataGrip and DBeaver, or query datasets directly through JSON APIs.
