3239
MariaDBERRORNotableGIS / SpatialHIGH confidence
Maximum number of points in geometry exceeded
Production Risk
Medium — spatial operation fails; may require geometry simplification pipeline.
Why it happens
- 1A spatial operation produced or attempted to store a geometry with more points than the allowed maximum.
- 2Densifying or buffering geometries may produce an excessive number of points.
How to reproduce
trigger — this will error
trigger — this will error
SELECT ST_Buffer(complex_polygon, 0.001, 128) FROM t1;
expected output
ERROR 3239 (HY000): Geometry has too many points. Maximum allowed is exceeded.
Fix 1
Reduce buffer resolution
Reduce buffer resolution
SELECT ST_Buffer(complex_polygon, 0.001, 16) FROM t1;
Why this works
Using fewer buffer points reduces the resulting geometry's point count.
Fix 2
Simplify the input geometry first
Simplify the input geometry first
SELECT ST_Buffer(ST_Simplify(complex_polygon, 0.0001), 0.001) FROM t1;
Why this works
ST_Simplify() reduces point count before the buffer operation.
