Geospatial Overview

FluentDynamoDB includes geospatial indexing support with three algorithms: Geohash, Google S2, and Uber H3.

Supported Algorithms​

Geohash​

  • Uses BETWEEN queries
  • Simple, efficient for rectangular regions
  • Good for general-purpose location queries

Google S2​

  • Hierarchical cell structure
  • Better for irregular shapes
  • Lightweight implementation (core functions only)

Uber H3​

  • Hexagonal grid system
  • Optimal for uniform coverage
  • Lightweight implementation (core functions only)

Compatibility​

Our S2 and H3 implementations provide core encoding/decoding functions. Codes are compatible with full-featured third-party libraries if you need advanced features like edge calculations or path functions.
