3.1.1 DB System Components

A DB System consists of the following components:

• An Amazon EC2 instance type (with resources defined by the associated shape. See Supported Shapes for more information.)

• Oracle Linux Operating System

  Note

  It is not possible to access the operating system. Only the MySQL instance is exposed through the DB System endpoint.

• MySQL Server Enterprise Edition 8.0. For more information, see Section 3.1.2, “MySQL Server”.

• Virtual Network Interface Card (VNIC) which attaches the DB System to a subnet of the Virtual Private Cloud (VPC). For connections to the DB System, a public endpoint is exposed as a fully-qualified domain name (FQDN). Specific IP addresses in CIDR format can be specified to limit access to the public endpoint.

• Network-attached block storage. MySQL HeatWave on AWS uses Amazon EBS block storage. For more information, see Amazon Elastic Block Store (Amazon EBS) in the Amazon EC2 User Guide for Linux Instances.

DB System Storage

Storage size should be determined based on your data size and performance requirements.

For information about increasing the storage available to the DB System, see Section 3.3.5, “Increasing DB System Storage”.

Supported Shapes

MySQL HeatWave on AWS supports the following MySQL and HeatWave node shapes.

Table 3.1 MySQL Shapes

Shape Name	vCPUs	Memory (GiB)
MySQL.2.16GB	2	16
MySQL.4.32GB	4	32
MySQL.8.64GB	8	64
MySQL.32.256GB	32	256

Table 3.2 HeatWave Node Shapes

Shape Name	Memory (GiB)
HeatWave.16GB	16
HeatWave.256GB	256

Note

If you intend to use HeatWave AutoML functionality, the HeatWave.256GB node shape is recommended when creating a HeatWave Cluster. The HeatWave.16GB node shape may not have enough memory for training on large data sets. If you see error messages about this (such as ML003024), use the larger shape instead.
