Database Proxy

I have a scenario where I want to perform database proxying (using multiple databases - Oracle; MSSQL; MySQL) etc.

 

I want to send to different pools based on read/write queries. I have seen there was a fair amount of chatter about this years ago (2013) but I haven't seen anything recently.

 

Is this something F5's can do? Are there any iApps or do you have to create a custom iRule?

 

Any help would be much appreciated!
