https://dev.mysql.com/geometry-well-formedness-validity.html
Spatial import functions that parse WKT or WKB values raise an error for attempts to create a geometry that is not syntactically well-formed. Spatial computations may detect some cases of invalid geometries and raise an error, but they may also ...

This section summarizes what has been added to, deprecated in, and removed from MySQL 8.0. A companion section lists MySQL server options and variables that have been added, deprecated, or removed in MySQL 8.0. See Section 1.5, “Server and Status ...
https://dev.mysql.com/gis-linestring-property-functions.html
If any geometry argument has an SRID value that refers to an undefined spatial reference system (SRS), an ER_SRS_NOT_FOUND error occurs. ST_IsClosed() handles its arguments as described in the introduction to this section, with this exception: If ...

It does support ORDER BY operations, BLOB columns, and spatial data types (see Section 11.5.1, “Spatial Data Types”). The ARCHIVE storage engine produces special-purpose tables that store large amounts of unindexed data in a very small ...
https://dev.mysql.com/st-geometry-columns-table.html
The ST_GEOMETRY_COLUMNS table provides information about table columns that store spatial data. This table is based on the SQL/MM (ISO/IEC 13249-3) standard, with extensions as noted. MySQL implements ST_GEOMETRY_COLUMNS as a view on the ...
https://dev.mysql.com/system-schema.html
It contains tables that store information required by the MySQL server as it runs. A broad categorization is that the mysql schema contains data dictionary tables that store database object metadata, and system tables used for other operational ...
https://dev.mysql.com/partitioning-limitations.html
Columns with spatial data types such as POINT or GEOMETRY cannot be used in partitioned tables. This section discusses current restrictions and limitations on MySQL partitioning support. The following constructs are not permitted in partitioning ...
https://dev.mysql.com/gis-class-geometrycollection.html
All the elements in a geometry collection must be in the same spatial reference system (that is, in the same coordinate system). Restrictions may be based on: Element type (for example, a MultiPoint may contain only Point elements) Dimension ... A ...
