MySQL Error 4026: Invalid AUTOEXTEND_SIZE Clause
Description
This error occurs when attempting to use the `AUTOEXTEND_SIZE` clause with a MySQL tablespace type that does not support this option. It typically indicates that the specified tablespace, such as an `UNDO` or `TEMPORARY` tablespace, cannot have its autoextend increment configured in this manner.
Error Message
AUTOEXTEND_SIZE clause is not valid for %s tablespace.
Known Causes
3 known causesUsing with UNDO Tablespaces
`UNDO` tablespaces are designed for transaction rollback and do not support the `AUTOEXTEND_SIZE` option for their data files.
Using with TEMPORARY Tablespaces
`TEMPORARY` tablespaces are used for intermediate operations and do not allow the `AUTOEXTEND_SIZE` clause to control their file growth.
Incorrect Tablespace Type
The `AUTOEXTEND_SIZE` clause is only valid for specific `InnoDB` tablespace types, such as general tablespaces or file-per-table tablespaces, not all tablespace types.
