DataWorks allows you to view MaxCompute, AnalyticDB for PostgreSQL, Hologres, and E-MapReduce tables in all workspaces of the current tenant account. You can filter tenant tables by the type and name of compute engine on the Tenant Tables tab.

Prerequisites

  • To view MaxCompute tenant tables, you must bind a MaxCompute project to the current workspace. For more information, see Configure a workspace.
  • To view AnalyticDB for PostgreSQL tenant tables, you must bind an AnalyticDB for PostgreSQL instance to the current workspace. After that, you must collect the metadata of the AnalyticDB for PostgreSQL instance by using the Data Map service. For more information, see Configure a workspace and Collect metadata from an AnalyticDB for PostgreSQL data store.
  • To view Hologres tenant tables, you must bind a Hologres instance to the current workspace. After that, you must collect the metadata of the Hologres instance by using the Data Map service. For more information, see Configure a workspace.
  • To view E-MapReduce tenant tables, you must bind an E-MapReduce cluster to the current workspace. After that, you must collect the metadata of the E-MapReduce cluster by using the Data Map service. For more information, see Configure a workspace and Collect metadata from an E-MapReduce data store.

    • The current environment is highlighted in blue.
    Table Name The name of the table in the corresponding project.
    Columns Displays the name, data type, and description of fields in the current table.
    Partitions Displays the partition information and number of partitions of the current table. A maximum of 60,000 partitions are supported. If you have specified the time-to-live (TTL) for partitions, the number of partitions depends on the TTL.
    Notice The partition information is displayed only for MaxCompute tenant tables.
    Preview Displays the data of the current table.
    Notice You can preview only the data of MaxCompute tenant tables.
