Better late than never, I just discovered that MariaDB and MySQL have a "new" DB engine called Aria since ... 8 years : [
en.wikipedia.org...]
It's an evolution of the MyISAM DB engine, developed by the same guy Monty, and his team.
For my usage, InnoDB, is not very convenient, and I was able to over optimize my code to exploit the MyISAM format , so I was a bit stuck between two chairs.
So, so far, Aria is pleasing me very much, and seems to be the best match, for my usage.
