MySQL 5.6: Bringing High Performance to the Table（mysql5.6）

With the continual growth and expansion of data, most organizations desire a database that meets their storage needs while remaining reliable and fast. That is why much attention has been given to MySQL 5.6 in recent years, a database technology designed to meet the demands of high performance. The latest iteration of MySQL 5.6 is designed to increase the speed and scalability of data while continuing to meet the reliability requirements.

MySQL 5.6 has multiple advanced algorithms to increase performance and scalability. It has improved buffer pool efficiency, enhancing the caching process, which allows more data to be read and written per unit of time. Furthermore, the memory bitmap algorithm, called “Page_track”, has advanced the Buffer Pool LRU Replacement Algorithm (BP-LRU) and the Adaptive Hash Index (AHI) to enable rapid lookup and navigation of data.

Moreover, MySQL 5.6 has a list of features that help increase performance. The InnoDB engine has improved scalability and better locking, while the MyISAM engine has increased support for compressed data types. For busy websites, the “Bulk InnoDB inserts” feature can be used to optimize the loading and unloading of data. Additionally, MySQL 5.6 incorporates improved support for stored procedures and functions that allows for more automation and speed.

MySQL 5.6 also includes query-rewriting capabilities, which allow users to simplify queries and improve their performance. Through the “stored rewrite rules”, the database will automatically in optimize the query and rewrite it in order to execute it faster. At the same time, the Dynamic Adaptive Query Optimization (DAQO) feature allows the query optimizer to select optimal access plans dynamically based on real-time data.

Finally, MySQL 5.6 also includes new privilege-management capabilities for a more robust security environment. All users can use “role-based authentication” to securely authenticate when accessing the database, while administrators can use the “schema-based privilege system” provides improved control over who has access to what data. Further, MySQL 5.6 provides enhanced support for “row-level security”, which allows users to control which rows of data to be returned when a query is executed.

MySQL 5.6 has many features that are designed to increase performance, scalability and reliability. With its advanced algorithms, improved memory management, increased query optimization capabilities, and enhanced security capabilities, MySQL 5.6 has the potential to revolutionize how an organization works with large scale databases.
