Performance: MySQL 8.0 is twice as fast as MySQL 5.7. MySQL 8.0 brings better performance in the following areas: read/write workloads, IO intensive workloads, and high competition workloads. NoSQL: MySQL has been providing NoSQL storage functionality since version 5.7, and this feature has also been greatly improved in version 8.0. This feature eliminates the need for an independent NoSQL document database, while MySQL document storage also provides multi document transaction support and complete ACID compliance for JSON documents in schema less mode. In addition, it also supports crash safe feature, where metadata is stored in a single transaction data dictionary. High Availability: InnoDB clusters provide integrated native HA solutions for your databases. Security: Improvements to OpenSSL, new default authentication, SQL roles, password strength, authorization.
