Last Updated:Jul 17, 2026

With subscription billing, you pay upfront to reserve resources and receive significant discounts.

Subscription

Item

Description

Use cases

Subscription is ideal for the following scenarios:

  • You can predict the resource usage period.

  • Your business workloads are stable.

  • You need long-term access to reserved resources.

Billing rules

  • CU fees = Number of CUs × Unit price × Subscription duration

  • Cloud disk storage fees = Storage capacity × ESSD price × Subscription duration

  • BE fees = Unit price of BE specifications × Number of BE nodes × Subscription duration

Billing cycle

The billing cycle matches your selected subscription duration and is based on the UTC+8 time zone. It starts when you create or renew an instance and ends at 00:00:00 on the day after the instance expires.

Renewal

An EMR Serverless StarRocks instance is suspended immediately upon expiration. The system automatically releases the instance 168 hours (7 days) after suspension. After release, the instance cannot be renewed. You can renew your instance anytime before it expires or is released. For more information, see Renewal instructions.

Billing examples

StarRocks shared-nothing instance (standard specifications)

The following table shows how to calculate the estimated total cost. This example assumes the region is China (Hangzhou), the purchased Instance Edition is the Standard, the BE specification type is Standard Specifications, the BE specifications are 8 CU, and the number of BE nodes is 3.

Final resource configuration:

  • FE compute resources: 24 CUs; Storage resources: 300 GB of ESSD PL1 (recommended).

  • BE compute resources: 24 CUs; Storage resources: 300 GB of ESSD PL1 (recommended).

Billing parameters

Cost (USD)

  • Compute resources (FE + BE): 48 CUs (24 + 24)

  • Unit price of CUs: USD 24.30 per CU/month

  • Storage resources (FE + BE): 600 GB (300 + 300)

  • Cloud disk type: ESSD PL1

  • Unit price of storage: USD 0.1530 per GB/month

  • Subscription duration: 1 month

Estimated total cost = CU fees + Cloud disk storage fees = 1,166.4 + 91.8 = 1,258.2

  • CU fees: Compute resources × Unit price × Subscription duration = (24 + 24) × 24.30 × 1 = 1,166.4

  • Cloud disk storage fees: Storage capacity × Unit price × Subscription duration = (300 + 300) × 0.1530 × 1 = 91.8

StarRocks shared-nothing instance (high-performance storage specifications)

The following table shows how to calculate the estimated total cost. This example assumes the region is China (Beijing), the purchased Instance Edition is Standard, the BE specification type is High-performance Storage, the BE specifications are 16 cores * 64 GB + 1 * 1788 GiB local SSD, and the number of BE nodes is 3.

Final resource configuration:

  • FE compute resources: 24 CUs; Storage resources: 300 GB of ESSD PL1 (recommended).

  • BE compute resources: 48 cores and 192 GiB of memory; Storage resources: 5,364 GiB of local SSD.

Billing parameters

Cost (USD)

  • FE compute resources: 24 CUs

  • Unit price of CUs: USD 24.30 per CU/month

  • FE storage resources: 300 GB

  • BE specifications: 16 cores, 64 GiB of memory, and one 1,788 GiB local SSD

  • Unit price of BE specifications: USD 567.59 per node/month

  • Number of BE nodes: 3

  • Cloud disk type (for FE): ESSD PL1

  • Unit price of cloud disk storage: USD 0.1530 per GB/month

  • Subscription duration: 1 month

Estimated total cost = CU fees + Cloud disk storage fees + BE fees = 583.2 + 45.9 + 1,702.77 = 2,331.87

  • CU fees (FE only): Compute resources × Unit price × Subscription duration = 24 × 24.30 × 1 = 583.2

  • Cloud disk storage fees (FE only): Storage capacity × Unit price × Subscription duration = 300 × 0.1530 × 1 = 45.9

  • BE fees: Unit price × Number of nodes × Subscription duration = 567.59 × 3 × 1 = 1,702.77

StarRocks shared-data instance

The following table shows how to calculate the estimated total cost. This example assumes you purchase a Standard instance in the China (Hangzhou) region, configured with 3 CNs at 8 CUs each.

Final resource configuration:

  • FE compute resources: 24 CUs; Storage resources: 300 GB of ESSD PL1 (recommended).

  • CN compute resources: 24 CUs; Storage resources: 150 GB of ESSD PL1 (recommended).

Billing parameters

Cost (USD)

  • Compute resources (FE + CN): 48 CUs (24 + 24)

  • Unit price of CUs: USD 24.30 per CU/month

  • Cloud disk storage resources (FE + CN): 450 GB (300 + 150)

  • Cloud disk type: ESSD PL1

  • Unit price of cloud disk storage: USD 0.1530 per GB/month

  • Unit price of data storage: USD 0.000036041667 per GB/hour

  • Subscription duration: 1 month

Estimated total cost = CU fees + Cloud disk storage fees = 1,166.4 + 68.85 = 1,235.25

  • CU fees: Compute resources × Unit price × Subscription duration = (24 + 24) × 24.30 × 1 = 1,166.4

  • Cloud disk storage fees: Storage capacity × Unit price × Subscription duration = (300 + 150) × 0.1530 × 1 = 68.85
