I will show you how to use these tools in a chained …. Following the recent post on replication performance and efficiency , I'd like to talk about another MySQL feature that has received some treatment in Aurora: the Query Cache. We'll first discuss the limitations of "traditional" Query Cache implementation, we will then watch a sysbench read-only test take off and go from K reads per second to nearly K reads per second, all thanks to the improved Query Cache.

Have fun! It makes perfect sense in typical OLTP applications especially web apps , where queries are quite repeatable because the same piece of data is often selected multiple times by many clients.

The following performance issues are associated with query cache implementation in vanilla …. How do you dig down into the JSON data, say like in comments on a blog post? This is a badly paraphrased question from Peter Zaitsev of Percona at the end of a recent presentation of mine at the Great Wide Open conference. Surely it can be done.

Can't it? Time to dig. I could not find an example of JSON data on a blog with comments.

This software features graphical user interface tools for managing your databases.

You can get Workbench in the Community and Standard editions. Adminer is another one of many GUI tools in this program. It can manage multiple databases and boasts various CSS skins for easier management.

Alternatively, you can interact with MySQL through the command-line interface. It comes with many tools for quick, easy management. MySQL Utilities is designed to tackle day-to-day maintenance and administration. Percona Toolkit automates repetitive tasks, speeds up your servers, and handles corrupt data.

This program is compatible with cloud infrastructure and distributed computing , creating a distributed and secure system of MySQL clusters by supporting cloud servers. It also features broad compatibility with all modern programming languages and management interface servers. As such, it enables you to share data existing in other bases, as well. MySQL runs on all operating systems and platforms in popular use.

As an extra, Oracle helpfully provides installers for Windows, Mac, and Linux. MySQL boasts many functions for database management.
