Updated April 2026. Benchmark SpatialBench results: spatial joins at scale Both WherobotsDB options complete all 12 SpatialBench query patterns at scale factor 1000. Apache Sedona completes six. The six it does not complete are zone statistics within a search radius (Q6), radius joins (Q8), polygon overlap detection (Q9), zone statistics through a spatial join (Q10), cross-zone trip counting (Q11), and KNN joins (Q12).

Read about WherobotsDB on SpatialBench. How to choose Your Sedona code comes with you Wherobots Cloud is the fastest way to run spatial in production, with WherobotsDB, RasterFlow, and the Havasu Catalog in one managed platform. Apache Sedona code runs on it without changes, and teams that must stay on their own Spark clusters run the same code on WherobotsDB BYOS. Raster and Earth intelligence Out-of-database raster comes with both WherobotsDB options. RasterFlow, Earth intelligence and perception as a service that turns imagery into physical-world features, runs in Wherobots Cloud. Spatial AI developer tools The Spatial AI Coding Assistant, MCP Server, and CLI come with Wherobots Cloud and put spatial analysis within reach of the whole team. Infrastructure control and data residency If compute must stay on your own infrastructure for compliance, procurement, or architecture reasons, WherobotsDB BYOS adds enterprise spatial without a managed platform.

Apache Sedona is the open-source spatial engine for Apache Spark, free under the Apache 2.0 license. Wherobots is the fully managed AI context engine for physical world data from the original creators of Sedona. It brings together WherobotsDB, the enterprise spatial runtime; RasterFlow, Earth intelligence and perception as a service that turns imagery into physical-world features; the Havasu Catalog of open datasets, RasterFlow models, notebooks, and apps next to your own data in Apache Iceberg; and Spatial AI developer tools, including the Spatial AI Coding Assistant for VS Code, the Wherobots MCP Server, and the Wherobots CLI. Apache Sedona code runs on Wherobots without changes. What is the difference between Apache Sedona and WherobotsDB? WherobotsDB is the enterprise spatial runtime from the original creators of Apache Sedona. It is 100% compatible with Sedona APIs and adds automatic query optimization, out-of-database raster, approximate KNN, and support SLAs. WherobotsDB runs on your own Spark clusters (BYOS) or fully managed in Wherobots Cloud. Is WherobotsDB compatible with Apache Sedona? Yes. WherobotsDB is 100% compatible with Apache Sedona APIs, so existing Sedona SQL and Python code runs without rewrites. Can I run WherobotsDB on my own Spark clusters? Yes. WherobotsDB Bring Your Own Spark (BYOS) is a drop-in runtime for existing Spark clusters, offered in the Enterprise edition. Data stays where it is and governance does not change. See pricing. Who builds Apache Sedona? The original creators of Apache Sedona are the founders of Wherobots. They continue to contribute to the project, which is maintained by the Apache Software Foundation community. What is SpatialBench? SpatialBench is an open benchmark for spatial query engines from the Apache Sedona project. It runs reproducible workloads such as point-in-polygon, range queries, spatial joins, and nearest-neighbor joins at multiple scale factors, so teams can compare engines on their own infrastructure. Does Apache Sedona support raster data? Yes, Apache Sedona processes rasters in memory. WherobotsDB adds out-of-database raster, which loads pixels on demand from object storage, and Wherobots Cloud adds RasterFlow for mosaics and computer vision inference over satellite and aerial imagery. Can Wherobots add a spatial function I need? Yes. Wherobots adds custom ST_ vector and RS_ raster functions for paying customers on request. Talk to us about your workload.
