SedonaDB

What SedonaDB is

SedonaDB is a free, open-source, single-node analytical database engine built around geospatial data. It is intended for smaller and medium datasets on a local machine or cloud instance; the project points to SedonaSpark, SedonaFlink, or SedonaSnow for distributed workloads. Its architecture uses columnar in-memory datasets, spatial indexing, coordinate-reference-system tracking, and Arrow format. Python and SQL interfaces are available, with an R package and SQL query function documented in the quickstart. Supported query types include spatial range, nearest-neighbor (KNN), spatial join, and KNN join. It interoperates with PyArrow-compatible tools such as GeoPandas, DuckDB, and Polars, and handles formats including GeoParquet, Shapefile, and GeoJSON. Documentation also demonstrates AWS S3 data and Iceberg tables through PyIceberg and Arrow. Memory-limited execution with automatic spill-to-disk is supported, but the default imposes no memory limit and does not spill. GPU-accelerated joins require a compatible build, NVIDIA CUDA 12 or later, and a qualifying NVIDIA GPU. The project is an Apache Sedona subproject under the Apache Software Foundation and uses the Apache-2.0 license.
