Sysbench test guide

Test design

• The following instance types are used in this test:
  • PolarDB-X 1.0 instance types:
    • Starter Edition 8-core 32 GB
    • Standard Edition 16-core 64 GB
    • Enterprise Edition 32-core 128 GB
    • Enterprise Edition 64-core 256 GB
  • One ECS stress testing instance: 32-core, 64 GB, compute network-enhanced, running the Aliyun Linux 2.1903 64-bit operating system
  • Twelve RDS instances: 16-core, 64 GB, MySQL 5.7, Dedicated
  Note PolarDB-X 1.0, ECS, and RDS instances are in the same zone and VPC.
• Create a database in the PolarDB-X 1.0 console. Use the horizontal splitting mode and select the 12 RDS instances.
• Install Sysbench on the ECS instance and prepare 160 million data records. For more information about how to use Sysbench, see the Sysbench user guide.
