MySQL has great reliability to perform well without requiring extensive troubleshooting due to bottlenecks or other slowdowns. It also incorporates a number of performance-enhanced mechanisms such as index support, load utilities, and memory caches. MySQL uses InnoDB as a storage engine, which provides highly efficient ACID-compliant transactional capabilities that assure high performance and scalability. To handle the rapidly growing database, MySQL Replication and cluster helps scale out the database.
