Learn about geometry function support in Databend
Geometry functions are a set of functions that handle spatial data types, such as geometric objects such as points, lines, and polygons. These functions are mainly used to perform spatial analysis and geographic data management. They are indispensable tools in geographic information systems (GIS), computer-aided design (CAD) and other application fields that require spatial data processing. They are used in geolocation services and real-time location. Analysis and other areas play an important role.
Databend has recently added a large number of geometric functions with the help of community members, especially @kkk25641463 . Databend official documentation is also actively updating relevant content. Welcome to visit Documentation/Test Support Coverage for details.

What's Up Next
We are always open to cutting-edge technologies and innovative ideas, and welcome you to join the community and inject vitality into Databend.
Support more MAP functions
MAP is a structured data type supported by Databend, which is used to save key-value pair data. Currently, Databend plans to add more functions suitable for MAP data types to help users better organize and process data with complex or unfixed structures, such as tags in user portraits or attributes in product analysis.
MAP_CAT(<map1>, <map2>)MAP_CONTAINS_KEY(<key>, <map>)MAP_DELETE(<map>, <key1>[, <key2>, ...])MAP_INSERT(<map>, <key>, <value>[, <updateFlag>])MAP_PICK(<map>, <key1>[, <key2>, ...]) or MAP_PICK(<map>, <array>)MAP_SIZE(<map>)
Issue #15295 | Feature: Support map functions
