What alternatives database engines are there to MySQL?

Unsure what alternatives there are to MySQL?

Looking for increases in MySQL performance?

You might not realize that there are some compatible relational database engines. That you can drop in to replace MySQL.

You can even run SQLite without needing a server stack.

SQLite is the most widely deployed database engine in the world

Each engine has it’s own pros and cons to consider before switching from one to another. Most are available as a drop in replacement for MySQL, but yet dropping out and back to MySQL may not be as smooth. Development of new versions means the code bases and features diverge from each other.

MariaDB, Percona Server and Amazon Aurora all offer performance improvements over vanilla MySQL. All for free:
