Dont understand MySQL requirements in HA setup

The HA setup docs specify that a requirement is

Run MySQL 5.7 withRun MySQL 5.7 with Barracuda where the default ROW_FORMAT is Dynamic

I dont know MySQL at all as my company uses a different RDBS. I am running mysql on AWS RDS, can anyone point me to how I enable “Barracuda where the default ROW_FORMAT is Dynamic”? I honestly have no idea what that even means.

If you’re using RDS those are things you can tweak with parameter groups and such, but the normal settings you get when asking for MySQL are fine.
