E-MapReduce:Billable items

Last Updated:Sep 24, 2025

This topic describes the billable resources and billing methods for E-MapReduce (EMR) Serverless StarRocks.

Billable item

Description

Compute CUs

The total computing resources for operations in StarRocks, such as data writes and queries, are measured in compute units (CUs). Fees vary based on the selected specification type. The following specification types are supported:

  • Standard: The default recommended specification. 1 CU = 1 CPU core + 4 GiB of memory. This configuration uses enterprise SSDs (ESSDs) as the storage solution for StarRocks.

  • Memory-enhanced: 1 RCU = 1 CPU core + 8 GiB of memory. This type is suitable for memory-intensive scenarios, such as those with many complex queries or high concurrent requests. ESSDs are used as the storage solution for StarRocks.

  • Network-enhanced: 1 NCU = 1 CPU core + 4 GiB of memory. The network bandwidth is more than double that of the standard specification. This type is suitable for scenarios that involve scanning large amounts of data in external tables. ESSDs are used for StarRocks storage.

  • High-performance Storage: Select detailed specifications as needed. This specification type uses local SSDs as data disks for StarRocks storage. It is suitable for scenarios with strict I/O performance requirements for storage.

  • Large-capacity Storage: Select detailed specifications as needed. This specification type uses local HDDs as data disks for StarRocks storage. It is suitable for scenarios with extremely large data volumes. This type can effectively reduce overall storage costs but has relatively low I/O performance requirements for storage.

Cloud disk storage

The amount of data that you store on cloud disks in StarRocks.

  • Shared-nothing Architecture: Includes the cloud disk data volume used for data storage by the actual frontend (FE) and backend (BE) nodes.

  • Shared-data Architecture: Includes the cloud disk data volume used for data storage by the actual FE nodes and the cloud disk data volume used for data caching by the compute nodes (CNs).

Elastic ephemeral disk storage

The amount of data that you store on elastic ephemeral disks in StarRocks. For more information about elastic ephemeral disks, see Elastic ephemeral disks.

Data storage

Data storage fees are incurred when you use a Shared-data instance. This data storage has lower performance than cloud disk storage.

If the Multi-zone Disaster Recovery feature is enabled for your Shared-data instance, the following fees are also incurred:

  • Additional FE nodes are required. This incurs extra CU fees, which are recorded as OBSERVER Compute Resources. For the unit price of these fees, see Compute CU fees.

  • Multi-zone backup for Object Storage Service (OSS) is enabled, which incurs extra storage fees. These fees are combined with the data storage fees and are not listed separately. For the unit price of these fees, see Data storage (multi-zone) fees.

Data backup

When you use a Storage-Compute Integrated Edition instance and enable the backup feature, you will incur data backup fees.

Specification fees

Important
  • For actual prices, see the product buy page.

  • Data storage fees apply only to Shared-data instances. Data storage supports only the pay-as-you-go billing method.

Billing methods

Billing method

Description

Subscription

Subscription is an upfront billing method. You pay for instances when you purchase them.

This billing method is ideal for long-term needs and is more cost-effective than pay-as-you-go. Longer subscription durations provide greater discounts. You can request a self-service refund for subscription instances. For more information, see Unsubscription rules for the international site.

Important

You cannot change the billing method of an instance from subscription to pay-as-you-go.

Pay-as-you-go

Pay-as-you-go is a post-paid billing method. The system generates a bill each hour based on the instance specifications. The fee is then deducted from your Alibaba Cloud account.

This billing method is suitable for short-term needs. For example, create a pay-as-you-go instance for testing. Delete the instance immediately after use to save costs.

Important

Computing resources are billed on an hourly basis even if no tasks are running in the instance.
