      Serverless Cloud Function (SCF)
      CKafka Data Reliability Description

      2. At the top of the page on the right, select Guangzhou for Region and select default in the Event Bus drop-down list.
      The Tencent Cloud service event bus collects monitoring and audit events generated by Tencent Cloud services in all regions. It is created in Guangzhou region by default and cannot be deleted.
      Select Event Bus on the left sidebar. In the event bus list, click default, and you can see that the default event bus already contains TencentDB for Redis®. For detailed directions, see Tencent Cloud Service Event Source.
      3. Click Create. On the Event Pattern page, configure parameters by referring to the following descriptions:

      Note:
