    4. Example

    Example1 Creating a Data Processing Task

    This example shows you how to create a data processing task. Similar to the open source component Logstash, data processing provides capabilities such as filtering, cleaning, anonymization, enrichment, and distribution of log data. Domain Specific Language (DSL) functions are implemented based on Flink for data processing, allowing you to easily process log stream data.

    Input Example

    POST / HTTP/1.1
    Host: cls.tencentcloudapi.com
    Content-Type: application/json
    X-TC-Action: CreateDataTransform
    <Common request parameters>
