who determines what "engines" are available in that D.B.? The server? Work bench? Can you download more engines?

Just wondering! :)

I was actually curious about the engines myself so I did a little bit of digging to find some answers.

Engines are responsible for doing the heavy lifting when it comes to manipulating the data. So there are different types of engines out there that are optimized for different tasks. For example, using myISAM instead of the default InnoDB engine results in faster, more memory efficient tables since it doesn't have to worry about backing up the tables as much. So using InnoDB would be a lot safer if you wanted to make sure that your data is not lost in any transaction.

As per your first question, I would say that MySQL ultimately decides the fate of each engine. It appears that the most recent engine that they added is the FEDERATED storage engine. You can look into it more here: https://dev.mysql.com/doc/refman/5.0/en/storage-engines.html To answer your second question, other storage engines may be available by third parties. You can look into it more here if you're interested: http://dev.mysql.com/doc/refman/5.7/en/storage-engines-other.html

Hope that helps!
