This option allows you to specify the maximum amount of temporary file space a connection can use before the request fails
because it exceeds the temporary file space limit. The temp_space_limit_check option must be set to On (the default) for the
max_temp_space option to take effect.
The default value 0 indicates that there is no fixed limit on the amount of temporary file space a connection can request.
Any other value specifies the number of bytes of temporary file space a connection can use. You can use k, m, or g to specify units of kilobytes, megabytes, or gigabytes, respectively. If you use p, the argument is a percentage of the total amount of temporary file space available.
For connections that request temporary file space, the database server checks the limit against the setting of the max_temp_space
option to make sure that the request is under the maximum size. If the connection requests more temporary space than is allowed,
the request fails and the error SQLSTATE_TEMP_SPACE_LIMIT is generated.
Can be set for an individual connection or for the PUBLIC group. Takes effect immediately. DBA authority required to set this
option for the PUBLIC group.
