  • Triggering Functions by Different Event Sources

    Triggering Functions by Different Event Sources

    OBS: Functions are triggered when operations, such as uploading, copying, and deleting objects, are performed on a bucket. For example, a function is invoked to compress and transform the images or videos uploaded to a specified bucket.

    SMN: Functions are triggered to process messages sent to a specified SMN topic.

    DIS: Functions are triggered to process the data uploaded to a specified DIS stream.

    DMS: Functions are triggered to process messages sent to a specified DMS queue.

    APIG: Functions are triggered to perform specified operations when a custom REST API is called.

    Timer: Functions are triggered according to configured rules.

    Manual invocation: You can manually invoke functions using an API or the console for debugging purposes.
