Last Updated:Mar 28, 2026

Sets the maximum number of segments used when splitting geometry objects to build the multi-bounding box (mbbox) spatial index.

Data type

Integer

Valid values

1 to 460. Default value: 400.

Description

The system automatically determines the optimal segment count for each geometry object during index construction and keeps it at or below this limit. You do not need to configure this parameter in most cases.

Example

Set the maximum number of segments for splitting objects for the current session.

SET ganos.geometry.mbbox_split_max_segments = 380;
