MariaDB

The question in the title is very general, but I'm more interested in specific application differences for programmers. Google also gives out a little bit different from what I want to find. And I want to know the answers to questions like this:

Is there something in the syntax of SELECT / INSERT / UPDATE / DELETE queries that MariaDB can do, but Percona can't?

In what cases do they noticeably differ in the work of the SELECT / INSERT / UPDATE / DELETE query optimizer on the InnoDb engine?

Are all MariaDB SQL functions (talking about functions like ifnull() etc.) supported by Percona?

As far as I know, nothing.
Differences at the level of new engines, replication and other advanced things.
