Real-time File Processing
Uploading files from a client to OBS triggers functions that create image thumbnails in real time, convert video formats, aggregate and filter data files, or implement other file operations.
Advantages
You will be billed only for the time it takes to process your files, and you will not be charged for idle resources when service demands are low.

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.
