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.
