If you complete "Step 3: Create Mapper and Reducer Functions and Test", and the test result meets the expectation, you can add COS configurations so that COS can publish events to SCF and call the function.

1) In the details page of the Mapper function you just created, select the Triggering Method tab, and click Add trigger mode.

2) Select COS trigger for the trigger method, srcmr created in Step 1: Prepare COS Bucket for COS Bucket, and File Upload for the event type, and then click Save.

In this way, you have completed all steps. You can test the configuration by following the steps below:

  1. Go to the COS Console, select src, upload a .txt text file, and check whether a similar file is generated in destmr after a certain period of time.
  2. You can monitor the function activities in the Serverless Cloud Function Console, and select Log to check the logs in which the calling of the function is recorded.
