While MySQL is known as an easy to use database, official tools to manage pools of MySQL servers and make the whole system highly available with less complexity have been typically missing from the picture. The introduction of MySQL Fabric makes all of this far simpler.  Join Abdul Manaf as he explains the latest developments for MySQL Fabric, a framework for managing pools of MySQL server. Using two applications, MySQL Fabric combines automated sharding with high availability. This webinar will demonstrate a broad overview of MySQL Fabric, what it can achieve, and how it’s used by DBAs, DevOps and developers. You will learn how MySQL Fabric provides a simple and effective option for high availability as well as the option of massive and incremental scale-out.  Plus, this webinar will help you understand the following topics: 

• MySQL Scaling, High Availability and Sharding
• MySQL …

Below are the key aspects that need to be part of your wishlist.

1) Leveraging Performance Schema(P_S) and SYS Schema

Performance Schema was introduced in MySQL 5.5.3 and further upgraded through version 5.7. It has its own storage engine, provides access to low-level server execution information while minimizing the impact on server performance. There is a trade-off between the time you can save by using Performance Schema and the load it adds to the server. It can optimize server performance and save time when used in an efficient manner.

Last week during the Oracle Users Group Leaders Summit in Bucharest I had the pleasure the meet the leaders for the MySQL Users Group from Azerbaijan,  Finland, Madrid and the Netherlands.

During some discussions, it appeared that some users are not aware of the Performance_Schema integration in MySQL Workbench. Indeed with WB you can enable PFS, add sys table if not present by default (<5.7).

You can use a default configuration or customize it and enable all the instruments and consumers you need.

When enabled, you can generate some useful reports

In case you are also not yet aware of it, the following dashboard is also available in MySQL Workbench

The latest version of MySQL Workbench has been released yesterday, June 13th : 6.3.7 GA
