Intro
This is the data era and most organizations are investing more in data
analytics. Data analytics needs more processing, memory, and
storage. To get a competitive advantage over other organizations invest
more to gain more performance, for analytics database performance is key. OLAP (Online Analytics processing) databases are more focused on
the fast retrieval of select operations. Database technologies are changing in
rapidly space, and new features are booming every quarter.
Oracle came up with a new invention for the MySQL database. MySQL HeatWave is
a fully managed database service powered by the HeatWave in-memory query
accelerator. It’s the only cloud service that combines transactions, real-time
analytics across data warehouses and data lakes, and machine learning in one
MySQL Database—without the complexity, latency, risks, and cost of ETL
duplication. It’s available on OCI, AWS, and Azure.
What is MySQL heatwave?
HeatWave uses a columnar in-memory representation that facilitates vectorized
processing. The use of columnar representation data is encoded and compressed
prior to being loaded in memory. This results in significant performance
improvements and a reduced memory footprint, which translates into reduced
costs for customers.
Figure 1: MYSQL heatwave columnar representation.
In this blog, I will elaborate on how you can test the query performance using
heatwave and non-heatwave.
OCI Heatwave architecture :
Figure 2 : OCI MYSQL heatwave architecture
This this blog our objective is to cover the below-mentioned sections.
Objectives
- Provision MySQL Database System in Oracle Cloud
- Enable HeatWave Cluster in MySQL Database
- Load Sample data into HeatWave Cluster
- Execute SQL Query to see the difference in performance and execution time.
Setup Network :
As the first step create a new VPN called "heatwave-VPN".
Figure 1: Create VPN
Add firewall rules :
Once the VPN creation is complete, let's add firewall rules which are required
for the mysql server connection.
1. Navigation Menu > Networking > Virtual Cloud Networks
2. Open heatwave-vcn
3. Click public subnet-heatwave-vcn
4. Click Default Security List for heatwave-vcn
5. Click Add Ingress Rules page under Ingress Rule
Figure 2: Add firewall rules.
Create Mysql DB and enable heatwave :
The next step is to create a MySQL environment with an enabling heatwave
feature. As this is for testing create a standalone server. To test the
heatwave feature make sure to enable heatwave configuration.
Figure 3 : Enable heatwave service
We are not enabling backup as this is a test server.
Once the MySQL database system creation is complete, it will appear in green
color.
chanaka_ya@cloudshell:~ (ca-toronto-1)$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/chanaka_ya/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/chanaka_ya/.ssh/id_rsa.
Your public key has been saved in /home/chanaka_ya/.ssh/id_rsa.pub.
Create a compute instance to log in to MySQL database service.
Create a computer instance called heatwave-client in a public subnet and copy the public key to the heatwave-client instance.
Now connect to the instance and install MySQL-shell, using MySQL-shell you can access the MySQL server.
chanaka_ya@cloudshell:.ssh (ca-toronto-1)$ ssh -i id_rsa opc@ip_address_of_client_instance

Add HeatWave Cluster to the DB system
To test this out, let's create a heat wave cluster. Navigate the MySQL database and click more-action to Add HeatWave cluster.
For this testing, we will create a heatwave cluster with 2 nodes. Each one consists of 1TB of memory.
Load to MySQL heatwave cluster
We can load data to the heatwave cluster using the "CALL sys.heatwave_load(JSON_ARRAY('mysql_customer_orders'), NULL);" command.
