MaxCompute:Computing pricing

You can subscribe to specific resources. MaxCompute reserves the resources that you subscribe to. Computing resources are measured in compute units (CUs). One CU is equivalent to 4 GB of memory and 1 CPU core. The subscription billing method is used for computing resources that are consumed by jobs, such as SQL, MapReduce, and Spark jobs.

MaxCompute calculates the fee for a standard SQL job based on the following formula:

Fee for a standard SQL job = Amount of input data in computing × SQL complexity × Unit price of a standard SQL job

The following table describes the unit price of a standard SQL job.

You can run the following command to calculate the complexity of an SQL job:

COST SQL <SQL Sentence>;

The following commands show an example on how to calculate the complexity of an SQL job.

odps@ $odps_project >COST SQL SELECT DISTINCT total1 FROM
(SELECT id1, COUNT(f1) AS total1 FROM in1 GROUP BY id1) tmp1
ORDER BY total1 DESC LIMIT 100;
Intput:1825361100.8 Bytes
Complexity:1.5

In this example, the number of keywords is calculated based on the following formula: 1 DISTINCT clause + 1 GROUP BY clause + 1 ORDER BY clause + MAX(0 - 1, 1) = 4. The complexity of the SQL job is 1.5. If the amount of data that needs to be computed is 1.7 GB, the fee is calculated based on the following formula:

1.7 × 1.5 × 0.0438 = 0.11 USD

You are charged for SQL jobs that reference external tables by using the following formula:

Fee for an SQL job = Amount of input data in computing × Unit price of SQL jobs that reference external tables

The following table describes the unit price of SQL jobs that reference external tables.

The SQL complexity is 1. On the following day, MaxCompute aggregates the fees for all executed SQL jobs into one bill within your Alibaba Cloud account.

You are charged for MapReduce jobs by using the following formula:

Fee for MapReduce jobs of the day = Number of billable hours × Unit price of a MapReduce job (USD per hour)

The following table describes the unit price of a MaxCompute MapReduce job.

The number of billable hours of a MapReduce job is calculated based on the following formula:

Number of billable hours of a MapReduce job = Number of hours for which a job runs × Number of CPU cores consumed by the job 

After a MapReduce job is run, MaxCompute calculates the billable hours of the job. On the following day, MaxCompute aggregates the fees for all executed MapReduce jobs into one bill within your Alibaba Cloud account. Then, MaxCompute deducts the fees from the balance of your Alibaba Cloud account.

Since February 1, 2019, you are charged for Spark jobs based on the pay-as-you-go billing method. For more information, see Spark on MaxCompute overview. You are charged for Spark jobs based on the following formula:

Fee for Spark jobs of the day = Number of billable hours × Unit price (USD 0.1041 per hour per job)

Take note of the following points:

• You must provide the number of CPU cores consumed, number of hours for which a job runs, and memory size.

• One billable hour is equivalent to 1 CPU core and 4 GB of memory.

After a Spark job is run, MaxCompute calculates the billable hours of the job. On the following day, MaxCompute aggregates the fees for all executed Spark jobs into one bill within your Alibaba Cloud account. Then, MaxCompute deducts the fees from the balance of your Alibaba Cloud account.

Since September 1, 2020, you are charged for MaxCompute Mars jobs based on the pay-as-you-go billing method. For more information, see Overview. You are charged for Mars jobs based on the following formula:

Fee for Mars jobs of the day = Number of billable hours × Unit price (USD 0.1041 per hour per job)

The number of billable hours for a Mars job is calculated by using the following method:

• Calculate the number of CPU cores and memory size that are consumed by the job.

• One billable hour is equivalent to 1 CPU core and 4 GB of memory.

• The number of billable hours of a Mars job is calculated based on the following formula: MAX[Number of CPU cores × Number of job running hours, ROUND UP(Memory size × Number of job running hours/4)].

  For example, if a Mars job that runs for 1 hour consumes 2 CPU cores and 5 GB of memory, the number of billable hours is 2 based on the following formula: MAX[2 × 1, ROUND UP(5 × 1/4)] = 2. If a Mars job that runs for 1 hour consumes 2 CPU cores and 10 GB of memory, the number of billable hours is 3 based on the following formula: MAX[2 × 1, ROUND UP(10 × 1/4)] = 3.

You are charged for MCQA jobs based on the following formula:

Fee for an MCQA job = Amount of input data for the MCQA job × Unit price (USD 0.0438 per GB)
