      This document summarizes the message structures of all trigger events that are connected to SCF. For more information on trigger configuration and restrictions, see Trigger Management.
      Note:
      The event structure of the input parameter passed in by a trigger has been partially defined and can be used directly. You can get and use the Java library through the Java Cloud Event Definition or the Go library through the Go Cloud Event Definition.

          }]
      }

      Event Message Structure for CKafka Trigger

      When a specified CKafka topic receives a message, the backend consumption module of SCF will consume the message and encapsulate it into an event in JSON format like the one below, which will trigger the bound function and pass the data content as input parameters to the function. For more information, see CKafka Trigger.
      {
        "Records": [
          {
            "Ckafka": {
              "topic": "test-topic",
              "partition":1,
              "offset":36,
              "msgKey": "None",
              "msgBody": "Hello from Ckafka!"
            }
          },
          {
            "Ckafka": {
              "topic": "test-topic",
              "partition":1,
              "offset":37,

              "msgBody": "Hello from Ckafka again!"
            }
          }
        ]
      }

      Event Message Structure for CMQ Topic Trigger

      When a specified CMQ topic receives a message, event data will be sent to the bound function in JSON format as shown below. For more information, see CMQ Topic Trigger.
      {
        "Records": [
          {
            "CMQ": {
              "type": "topic",
              "topicOwner":"120xxxxx",

          }
        ]
      }

      Event Message Structure for CLS Trigger

      When the specified CLS trigger receives a message, the CLS backend consumption module will consume the message and encapsulate it to asynchronously invoke your function. In order to ensure the efficiency of data transfer in a single triggering action, the value of the data field is a Base64-encoded ZIP document. For more information, see CLS Trigger.
      {
        "clslogs": {
          "data": "ewogICAgIm1lc3NhZ2VUeXBlIjogIkRBVEFfTUVTU0FHRSIsCiAgICAib3duZXIiOiAiMTIzNDU2Nzg5MDEyIiwKICAgICJsb2dHcm91cCI6I..."
        }
      }
      After being decoded and decompressed, the log data will look like the following JSON body (using decoded CLS Logs message data as an example):
      {
          "topic_id": "xxxx-xx-xx-xx-yyyyyyyy",
          "topic_name": "testname",
          "records": [{
              "timestamp": "1605578090000000",
              "content": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
          }, {
              "timestamp": "1605578090000003",
              "content": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
          }]
      }

      Event Message Structure for MPS Trigger

      When a specified MPS trigger receives a message, the event structures and fields will be as shown below (with the WorkflowTask task as an example). For more information, see MPS Trigger.
