Hi there, I’m sure this has been asked many a times; if so please point to the preexisting topics.

So what are the limitation of using MySQL Community Edition as the tag historian?  
(that’s the one I’m using in Ignition University)  
Where can I find the comparison between various database platforms that Ignition supports?

Thanks!
