This is the third episode of “Discovering MySQL Database Service“, a series of tutorials where I will show you, step by step, how to use MySQL Database Service and some other Oracle Cloud Infrastructure services.

In the previous episode we’ve created our compartment, the foundation stone, of the architecture that we will build during this Discovering MySQL Database Service journey.

In this episode, we’ll see what is a Virtual Cloud Network (VCN) and how to create one and use it.

In the previous episode we've introduced the different components that we will use during this Discovering MySQL Database Service journey.

In this episode, we'll see what is a compartment and how to create one and use it in order to create a MySQL DB system.

If you have (too) long running select queries it is probably because of lack of relevant indexes, problematic schema that lead to poor queries or inadequate hardware.

That said, sometime even if you doing it right, the query execution time could be too long regarding of what the application or your users expect. It is often true for reporting, real time analytics or BI queries.

At Oracle we have developed Heatwave, that allow you to easily run high performance analytics against your MySQL database.

To be more precise, Heatwave is a massively-scalable integrated analytics engine for MySQL Database Service (MDS), the MySQL DBaaS in Oracle Cloud Infrastructure (OCI).

Some key points of Heatwave:

- Single MySQL database for OLTP & analytics applications
- All existing applications work without any changes
- Extreme performance:
+ 400x faster than MySQL, scales to thousands of cores …

Since MySQL 8.0.22 there is a mechanism in asynchronous replication that makes the receiver automatically try to re-establish an asynchronous replication connection to another sender, in case the current connection gets interrupted due to the failure of the current sender.
