PolarDB:Usage notes

Last Updated:Aug 25, 2026

GanosBase Geometry Pyramidcan be used for fast display of 2D spatial geometry big data.

Data requirements

  • Spatial data tables of type Point, Line, Polygon, MultiPoint, MultiLine, or MultiPolygon.

  • Each record must have a unique positive integer ID field (uint4/uint8).

  • A spatial index must have been created for the geometry field.

  • Geometry data supports any EPSGcoordinate system. MVT output supports EPSG:3857/EPSG:4326coordinate systems.

Hardware requirements

  • Recommended for 100M records: 32-core CPU, 64 GB RAM, 500 GB SSD. ~15 min processing time.

  • Extra pyramid storage typically ≤ 1/10 of original data.
