MariaDB innodb Tablespace on a Raspberry Pi

Hi Everyone, I'm on a very steep learning curve here, just hoping someone on here may be able to answer my question.

I understand most databasey things having been a Visual FoxPro developer in the past, and have installed MariaDB on to a Raspberry Pi. I am using Node-Red all working very well.

The question I have is about table file sizes.

On the Pi in the "50-server.cnf" file which replaces the "mysql.cnf" it states "# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/". So this got me wondering about table sizes for my data files as my database will ultimately hold only 10 tables but several with a possible 500,000 small (4-10 columns) records. I will move the database folders off to an SSD when development has finished. (whenever that may be!).

I have found that the site MariaDB Knowledge Base is a fantastic resource but my question is still unanswered.

Does the statement "# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/" only refer to the "ibdata1" table?

ibdata1:12M:autoextend (from MariaDB 10.0), ibdata1:10M:autoextend (before MariaDB 10.0)

There is a reference to the increment value " innodb_autoextend_increment" which states " this setting does not apply to the resulting per-table tablespace files, which are automatically extended in their own way."

I'm at the point where I believe I'm overthinking this and it seems it will take care of itself. Anybody able to put my mind at rest?

To help others:

I have found that the "MySQL Workbench" is an excellent gui for administering the databases on my Pi from my windows desktop.

The "50-server.cnf" file replaces the "mysql.cnf" for configuring the installation. This is where the bind-address setting amongst many others is now to be found.

Cheers. Paul.
