PostGIS and Redis GEO combo yields 100x faster spatial queries
A developer optimized spatial search queries from 8 seconds to 80ms by combining PostGIS with a projected coordinate system and Redis GEO. The initial PostGIS query on 10,000 points took 7.8 seconds due to SRID issues. Adding Redis GEO as a pre-filter reduced query time to under 100ms.
