December 4, 2025 - Additional notes on CLONE TABLE limits

Dear MaxCompute user,

• You cannot use the CLONE TABLE command to copy table data between projects with different storage classes. For example, you cannot use the CLONE TABLE command to copy a table from a project with a multi-AZ storage class to a project with a single-AZ storage class, or vice versa.

• Data replicas are distributed differently in multi-AZ and single-AZ projects. As a result, a full table copy cannot be completed quickly by only CLONE TABLE copying metadata. You must wait for the data to be completely rewritten across availability zones (AZs) in the background.

• Recommended solutions for copying tables between projects with different storage classes:

  • For non-partitioned tables, use CREATE TABLE AS to migrate data.

  • For partitioned tables, first create a table with CREATE TABLE LIKE, and then execute INSERT OVERWRITE to migrate the data.

If you have any questions or need technical support, please submit a ticket.

September 16, 2025 - Append Delta Table release announcement

Dear MaxCompute user,

Delta Table now supports Append Delta Table for non-primary key tables. The original Delta Table only supported primary key tables. Now, the primary key tables in Delta Table are named PK Delta Table.

Delta Table is a high-performance table format developed by MaxCompute for large-scale analytical datasets. This table format includes two types: Append Delta Tables (without primary keys) and PK Delta Tables (with primary keys). It supports features such as atomicity, consistency, isolation, and durability (ACID) transactions, incremental queries, time travel queries, dynamic cluster bucketing, real-time data updates, and schema evolution.

The MaxCompute platform provides native data lakehouse and near-real-time computing capabilities. You can use standard SQL to create, update, and query Delta Tables without managing the complex underlying storage and metadata. MaxCompute automatically maintains and optimizes these components to provide a balance between ease of use and cost-effectiveness.

The new Delta Table format provides the following benefits:

• Balances data freshness and query efficiency for real-time services.

• Overcomes the limitations of previous table formats to support business growth.

• Balances performance and reliability.

September 10, 2025 - MaxCompute exclusive resource groups for data transmission to support multiple level-2 quotas

Dear MaxCompute user,

MaxCompute will upgrade the quota management feature for exclusive resource groups for data transmission. The upgrade will start at 19:00 on Wednesday, September 17, 2025 (UTC+8). After the upgrade:

• The quota configuration for the MaxCompute Data Transmission Service will be fully aligned with the configuration for computing resource quotas. This lets you manage different types of resources with a single set of rules.

• You can create multiple level-2 quotas under a single level-1 quota. This lets you share purchased resources across different services while maintaining resource fencing. You can also set flexible configuration plans and schedules based on service usage patterns, such as during peak and off-peak hours, to prevent resource waste and reduce costs.

The version prior to this upgrade does not support configuration plans and schedules. If you already use the time-sharing feature of the Data Transmission Service, the system will generate a corresponding configuration plan for you. This ensures that the upgrade does not affect your service. You can go to the console to view and modify the plan.

Thank you for choosing Alibaba Cloud.

July 25, 2025 - Unpublishing of the reverse VPC access feature for MaxCompute Spark

Dear MaxCompute user,

The reverse VPC access solution for Spark is being phased out due to technology upgrades. MaxCompute will unpublish this feature on September 30, 2025 (Tuesday) (UTC+8). After this date, you can no longer use this feature for new jobs.

Upgrade your existing MaxCompute Spark reverse VPC access configuration to the direct connection over leased line method as soon as possible. The new method is more stable, performs better, and is more cost-effective. The upgrade steps are as follows:

1. Enable network connectivity over a leased line.

   For more information, see VPC access solution (direct connection over leased line).

2. Modify the configuration parameters for your Spark job to access the VPC network over a leased line.

   • If you used the reverse VPC access method, your Spark job was configured with the spark.hadoop.odps.cupid.vpc.domain.list parameter. The following is an example of the parameter:

     Parameter example

     {
       "regionId":"cn-beijing", 
       "vpcs":[
         {
           "vpcId":"vpc-2zeaeq21mb1dmkqh*****",
           "zones":[
             {
               "urls":[
                 {
                   "domain":"hb-2zecxg2ltnpeg8me4-master*-***.hbase.rds.aliyuncs.com",
                   "port":2181
                 }
               ]
             }
           ]
         }
       ]
     }
     

   • To switch to the direct connection over leased line method, add the following two configuration parameters to your Spark job. Replace RegionID and VPCID with the actual values.

     # Add the following configurations to the /spark-defaults.conf file in DataWorks configuration items.
     spark.hadoop.odps.cupid.eni.enable = true
     spark.hadoop.odps.cupid.eni.info = <regionid>:<vpcid>

     Example:

     # For the preceding reverse VPC access example, add the following configuration parameters.
     spark.hadoop.odps.cupid.eni.enable = true
     spark.hadoop.odps.cupid.eni.info = cn-beijing:vpc-2zeaeq21mb1dmkqh*****

     After the configuration is complete, the following information is displayed in the Logview for the Spark job. This indicates that the job now accesses the VPC using the "direct connection over leased line" method.

Thank you for choosing Alibaba Cloud.

July 24, 2025 - MaxCompute network connectivity solution upgrade

Dear MaxCompute user:

The underlying technology of MaxCompute's network connectivity feature in China public cloud regions will upgraded from Monday, July 14 to Thursday, July 31, 2025 (UTC+8). The upgrade includes the following changes:

• Before the upgrade (current solution): Two Elastic Network Interfaces (ENIs) are created in your virtual private cloud (VPC).

• After the upgrade (new solution): The system automatically creates two reverse endpoints (PVLs) and two security groups to manage the security rules for the PVLs. This process establishes network connectivity for MaxCompute.

After the new network solution is published, two PVLs will appear on the Endpoint page in the VPC Management Console and two security groups on the Network Security > Security Group page in the ECS Console (as shown in the following figures). Additionally, you will receive a notification that PrivateLink is enabled.

This change is an upgrade to strengthen the network architecture and will not affect your services or fees. For more information about the features, see Network connection process.
