In MaxCompute, you can create a Hologres external table in dual-signature authentication mode. This feature helps significantly improve the efficiency of creating external tables.
Target customers: customers who want to use real-time data warehousing and offline data warehousing and customers who want to perform online data analytics.
Features released: The dual-signature authentication mode is an authentication protocol that is developed based on MaxCompute and Hologres. After the user logon information and signature are used on MaxCompute, authentication data is sent to Hologres. Then, Hologres performs authentication by using the same username based on the protocol that is compatible with the underlying layer of MaxCompute. This way, you can directly access external tables if you use the same Alibaba Cloud account to access MaxCompute and Hologres. You do not need to configure additional authentication information.

MaxCompute allows you to use the CREATE TABLE LIKE statement to create a table that has the same schema as a table in external data sources.
Target customers: data analysts, data developers, and data platform-related personnel who want to use the MaxCompute lakehouse solution to create a MaxCompute table that has the same schema as a table in external data sources such as E-MapReduce (EMR), Hadoop, and Data Lake Formation (DLF).
Features released: This feature allows you to use the MaxCompute lakehouse solution to create a MaxCompute table that has the same schema as a table in external data sources such as EMR, Hadoop, and DLF. You can use the CREATE TABLE LIKE statement to migrate table schemas from external data sources to MaxCompute. This helps improve data governance and access performance.
