Deploying the UDF Plugin Batch Processing

Based on the row-by-row processing deployment, perform the following steps on the management node and all compute nodes:

1. Configure batch processing parameters in the omni.conf file on all nodes.
   1. Select Command Execution and click Add a Task.

      

   2. Set task 1 parameters and click Save.

      Table 1 Task 1 parameters

      Parameter	Description
      Task Name	Configure batch processing parameters in the omni.conf file.
      Task Description	Configure batch processing parameters in the omni.conf file on all nodes.
      Run Directory	/opt/omni-operator/conf
      Run Command	sed -i '/enableBatchExprEvaluate/d' /opt/omni-operator/conf/omni.conf; echo "enableBatchExprEvaluate=true" >> /opt/omni-operator/conf/omni.conf;

      

      If enableBatchExprEvaluate is set to true, OmniOperator batch processing is enabled. If it is set to false, OmniOperator batch processing is disabled. The default value is false.

      

2. Export the service flow and save it to your local PC. You can import service flows to quickly install other components.
   1. In the upper right corner of the displayed page, click Export.

      The window for selecting a path for saving the template is displayed.

      

   2. Name the template OmniOperator UDF Plugin Batch Processing Deployment and Configuration Workflow and click Save.

      

3. Execute the service flow.

   Click Finish in the lower right corner and select Run Service. The procedure is complete when the execution is successful.
