The "Inward and Outward Tables" page needs further clarification regarding INWARD tables

The "Inward and Outward Tables" page:

https://mariadb.com/kb/en/mariadb/inward-and-outward-tables/

Needs further clarification on INWARD tables.

Specifically, it needs to state which kinds of CONNECT table types can be used. As it is, one would think all CONNECT table types would be an option, but that isn't the case.

To even realize this, you have to dig some...

For instance, on this page:

https://mariadb.com/kb/en/mariadb/creating-and-dropping-connect-tables/

It says:

FILE_NAME : The file (path) name for all table types based on files. Can be absolute or relative to the current data directory. If not specified, this is an Inward table and a default value is used.

So, the CONNECT table type must be a type based on files. This would exclude the MYSQL type - the only clear example I could find for a CREATE TABLE.

However, this raises a new question as to what all CONNECT table types are based on files?

This question also needs addressed.

There are a slew of CONNECT table type, listed here:

https://mariadb.com/kb/en/mariadb/connect-table-types/

So a chart on which are file based and which are not would be ideal.

Thank you.
