PolarDB:ganos.geometry.mbbox_split_points

Last Updated:Mar 28, 2026

Controls the number of points per segment when splitting geometry objects to build the multi-bounding box (mbbox) spatial index.

Data type

Integer

Valid values

2–100000. Default: 100.

Description

This parameter works together with ganos.geometry.mbbox_split_max_segments. If the number of resulting segments would exceed the limit set by ganos.geometry.mbbox_split_max_segments, Ganos recalculates the segment size using this formula:

points per segment = total points / max segments

Example

Set the number of points per segment for the current session:

SET ganos.geometry.mbbox_split_points = 150;
