![]() Server Setup and Environmentįor this benchmark, I intend to use a minimal setup for production using the following AWS EC2 environment: This blog post won’t be discussing the features of MySQL 8.0, but intends to benchmark its performance against MySQL 5.7 and see how it has improved then. With all of these cool features, enhancements, improvements that MySQL 8.0 offers, our team was interested to determine how well the current version MySQL 8.0 performs especially given that our support for MySQL 8.0.x versions in ClusterControl is on its way (so stay tuned on this). Security has been improved with the new addition of caching_sha2_password which is now the default authentication replacing mysql_native_password and offers more flexibility but tightened security which must use either a secure connection or an unencrypted connection that supports password exchange using an RSA key pair. Unlike previous versions, dictionary data was stored in metadata files and non-transactional tables. It’s now incorporated with a transactional data dictionary that stores information about database objects. ![]() Tons of new features have been added such as CTE (Common Table Expressions), Window Functions, Invisible Indexes, regexp (or Regular Expression)–the latter has been changed and now provides full Unicode support and is multibyte safe. For instance, *.frm, *.TRG, *.TRN, and *.par no longer exist. You can get back to the procedure source code by double-clicking the procedure in the Call Stack window.Ī green arrow indicates that you have stepped back to the parent code that has called the trigger.MySQL 8.0 brought enormous changes and modifications that were pushed by the Oracle MySQL Team. You may notice the yellow arrow next to the ScheduleDetail trigger which identifies the stack frame where the execution pointer is currently located. There are two database objects in the Call Stack window: the ScheduleDetail trigger and the FillSchedule procedure. Step through the trigger until you exit back to the stored procedure, and continue to the end. At the INSERT INTO schedule_list statement, when you press F11 again, you will step into the trigger. Step through the code using the F11 key or the Step Into option, or press CTRL+F5 to move directly to the breakpoint. In the Edit Parameters window, enter input values for the procedure and click OK.On the Standard toolbar, click Start Debugging.Switch to the SQL view, right-click in the gray margin next to the INSERT INTO schedule_list statement, and then click Insert Breakpoint on the shortcut menu. In Database Explorer > Procedures folder, double-click the FillSchedule procedure to open it.The stored procedure will be successfully compiled with debug info. In the Procedures folder, right-click the procedure you want to debug and click Compile > Compile for Debugging on the shortcut menu.This step is obligatory: if you do not set a breakpoint in the trigger, you will skip over its code when you try to step into it. ![]()
