HeatWave – A MySQL cloud feature to speed up your queries

April 13, 2021
Tags: , , ,

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
+ 1100x faster than Amazon
Aurora
+ 2.7x faster than Amazon Redshift

Replicate from MySQL 5.7 to MySQL Database Service

January 26, 2021

MySQL Replication is a very common topology, widely used in various architecture.
People use it, among others, for High Availability, Read Scalability or Geographic Redundancy.

Another use case is to use MySQL Replication to seamlessly integrate a newer version of the server in your architecture.
Let’s say you are running MySQL 5.7 then you can easily setup a 8.0 instance as a replica of your 5.7.

Extending this idea it is also possible to replicate your MySQL 5.7 (or 8.0 obviously) to a MySQL Database Service instance, the true MySQL PaaS on Oracle Cloud Infrastructure.
