MySQL 8.0 Features Galore: For Manageability & Performance
Author: Srinivasa Krishna | | October 11, 2019
MySQL 8.0 offers impeccable performance boost as compared to 5.7. From automated upgrades to Optimizer functions, 8.0 is not the usual cherry on top update. Let’s jump quickly into some of the features that can improve the performance of systems and applications using MySQL.
The SQL InnoDB cluster integrates SQL Shell, MySQL Router and Group Replication with MySQL server to minimize over-reliance on external tools to perform certain transactions. As such, it uses global transaction identifiers (GTIDs), multithreaded slave execution, Performance Schema and binary logs to maximize CPU performance. Servers now have a self-healing process allowing them to rejoin its group automatically after a period of downtime.
The new transactional data dictionary combined with binary logs allows for a reliable DB system. It enables faster data recovery process as it is crash-safe and centralized. Atomic DLL statements are stored as a single metadata file. This platform with sufficient resources unlike previously where several scripts demanded its own resources.
InnoDB is a powerful tool that reads and writes IO-bound and high contention workloads quickly. The Resource Group enables users to allocate resources to various table executions. Also, 8.0 enable you to use every storage device to its full power by eliminating the previous fil_system_mutex global lock.
With the new version, you can mark indexes as visible or invisible. As such, you will be able to avoid making unintended changes to certain indexes. The Optimizer ignores the indexes marked invisible when executing queries. Also, you have full control over Undo Tablespaces, meaning you can optimize transactional data to suit your needs.
Version 8.0 enables information schemas to be used by external tools. The implementation process is much easier as schema tables are presented as simple views. You can now add more than 100 indexes schema queries on schema tables, thus bolstering performance.
Client Error Reporting
With MySQL 8.0, you can view aggregated client error counts reported by the server. You view the errors across various parameters like number, type, date, and time. Other important manageability features introduced in 8.0 include the statement latency histograms, remote management, SET PERSIST for global variables and data locking dependencies graph. MySQL 8.0 comes with a swath of features and performance improvements.
MySQL 8.0 is an invaluable tool as it is void of the issues that sully version 5.7. When you’re ready to upgrade from version 5.7, you can leverage the help of our experts. We use DevOps principles of automation, culture, integration, and performance to maintain databases in client’s servers and applications.
