MariaDB Vs MySQL In 2019: Compatibility, Performance, And Syntax

1

MySQL

MySQL: MySQL is an open-source relational database management system (RDBMS). Just like all other relational databases, MySQL uses tables, constraints, triggers, roles, stored procedures and views as the core components that you work with. A table consists of rows, and each row contains a same set of columns. MySQL uses primary keys to uniquely identify each row (a.k.a record) in a table, and foreign keys to assure the referential integrity between two related tables.MariaDB: Since MariaDB is a fork of MySQL, the database structure and indexes of MariaDB are the same as MySQL. This allows you to switch from MySQL to MariaDB without having to alter your applications since the data and data structures will not need to change.This means that:

MariaDB

Even the command line tools are similar to mysqldump and mysqladmin still having the original names, allowing MariaDB to be a drop-in replacement.To make sure MariaDB maintains drop-in compatibility, the MariaDB developers do a monthly merge of the MariaDB code with the MySQL code. Even with this, there are some differences between MariaDB and MySQL that could cause some minor compatibility issues.Bill Karwin, author of SQL Antipatterns: Avoiding the Pitfall, believes that MySQL still has a lot of potential and will eventually diverge from MariaDB.
