You can configure the rules engine data forwarding function to forward data to Table Store.


Before you configure forwarding, complete the following tasks:
  • In the IoT Platform console, create a forwarding rule and write SQL statements for data processing.

    For more information, see Configure data forwarding rules.

    In this example, the following SQL statement is defined:
    SELECT deviceName as deviceName, items.PM25.value as PM25, items. WorkMode.value as WorkMode 
    FROM "/sys/a1ktuxe****/aircleanerthing/event/property/post" WHERE
  • In the Table Store console, create instances and tables for data receiving and storage.

    For more information about Table Store, see Table Store documentation.


  1. On the details page of the rule, click Add Operation in the Data Forwarding section.
    Note Binary data cannot be forwarded to Table Store.
  2. In the Add Operation dialog box, select Save to Table Store and set parameters as prompted, and then clickOK.
    Parameter Description
    Select Operation Select Save to Table Store.
    Region Select the region of the Table Store instance that receives data.
    Instance Select the Table Store instance that receives data.
    Data Sheet Select the table that receives data..
    Primary Key To set the value for a primary key of the table, you must use the corresponding field value in the SELECT statement of the forwarding rule. When data is forwarded, this value is saved as the value of the primary key.
    • You can set this parameter in the format of ${}. For example, ${deviceName} indicates that the value of the primary key is the value of DeviceName in the message.
    • If the primary key is an auto-increment column, you do not need to specify the value for the primary key. Table Store automatically generates a value for this primary key column. Therefore, the value of an auto-increment primary key is automatically set to AUTO_INCREMENT and cannot be modified.

      For more information about auto-increment primary keys, see Auto-increment function of the primary key column.

    Role Authorize IoT Platform to write data to Table Store.

    You must create a role with Table Store write permissions in the RAM console and assign the role to IoT Platform.

  3. Go back to Data Forwarding page, click Start corresponding to the rule to start the rule.
  4. Simulate data push to test data flow.
    1. In the left-side navigation pane of the IoT Platform console, choose Maintenance > Online Debug.
    2. Select the device for debugging, and use a Virtual Device to push analog data to IoT Platform. For more information, see Debug virtual devices.
    3. After the data is pushed, go to the Data Editor page of the target table in the Table Store console to check whether the specified data has been received.
