This topic describes how to activate Lindorm Distributed Processing System (LDPS) for an ApsaraDB for Lindorm (Lindorm) instance and how to modify the configurations of LDPS. LDPS is a compute engine service provided by Lindorm.

Prerequisites

A Lindorm instance is created. For more information, see Create an instance.

Billing method

Computing resources can be elastically scaled based on the computing workloads. You are charged for the computing resources based on your actual resource usage. Computing resources are measured in compute units (CUs). One CU equals one core and 4 GB of memory. One CU costs CNY 0.364 per hour.

Activate LDPS

  1. In the left-side navigation pane, click Database Connections.
  2. Click the Compute Engine tab, and click Activate Now.
    Active LDPS
  3. Configure the Maximum Elastic Resources parameter.
    resource-max
    Note This parameter specifies the size of the resource pool of LDPS. You are charged based on the actual resource usage.
  4. Read and agree to the terms of service.
  5. Click Buy Now. Then, the status of the Lindorm instance is changed to Scaling. The configuration takes effect in 5 to 10 minutes.
  6. Optional:After LDPS is activated, you can click Apply for Public Endpoint on the Compute Engine tab to apply for a public endpoint.

Modify the configurations of LDPS

LDPS provides scalability. You can change the upper limit of resources to resize the resource pool.

  1. In the Configurations section, find the configuration parameter of LDPS, and choose Manage > Update Upper Limit of Resources.
  2. Change the value of the Maximum Elastic Resources parameter based on your business requirements.
  3. Read and agree to the terms of service.
  4. Click Buy Now. Then, the status of the Lindorm instance is changed to Scaling. The updated configuration takes effect in 5 to 10 minutes.
