HoloWeb allows you to synchronize MaxCompute data with a few clicks in a visualized manner. This helps you query data in MaxCompute tables. This topic describes how to use HoloWeb to create a MaxCompute data synchronization task and view the status information about the task in the HoloWeb console.

Prerequisites

  • An Alibaba Cloud account is created.
  • Real-name verification is completed.
  • A Hologres instance is purchased. For more information, see Purchase a Hologres instance.

Create a MaxCompute data synchronization task

Create a MaxCompute data synchronization task. For more information, see Synchronize MaxCompute data with a few clicks.

View the information about the MaxCompute data synchronization task

  1. Connect the purchased Hologres instance to HoloWeb. For more information, see Manage a connection.
  2. On the HoloWeb page, click System Management in the top navigation bar.
  3. In the left-side navigation pane, choose Data Synchronization > Synchronization MaxCompute data.
  4. On the Synchronization MaxCompute data page, set the parameters as required and click Query.
    The following table describes the parameters.
    Parameter Description
    Connection name The name of the required connection.
    Database The name of the Hologres database.
    Status Valid values:
    • Running: indicates that the synchronization task is running.
    • Succeeded: indicates that the synchronization task has been executed.
    • Failed: indicates that the synchronization task failed to be executed.
    • Interrupted: indicates that the synchronization task is interrupted.
    If you do not set the Connection name, Database, and Status parameters, all MaxCompute data synchronization tasks that are created under the current account are displayed.
    In this example, you can set the Status parameter to Succeeded to view the synchronization tasks that are in the Succeeded state, as shown in the following figure.You can perform the following operations on these tasks:
    • View detailed information about a synchronization task.

      Find the required synchronization task and click Details in the Operation column to go to the MaxCompute data synchronization details page. All detailed information about the task is displayed, as shown in the following figure.

    • Rerun a synchronization task.

      Find the required synchronization task and click Rerun in the Operation column to rerun the task.

      If you want to interrupt the task that is rerun, click Stop in the Operation column.

    • Delete a synchronization task.

      Find the required synchronization task and click Delete in the Operation column to delete the task.

    • View the execution history of a synchronization task.

      Find the required synchronization task and click Execution history in the Operation column to view the execution information about each SQL statement in the task. For example, you can view whether the SQL statement is successfully executed and the execution duration of the SQL statement, as shown in the following figure.You can directly click an SQL statement to copy it.
