I have an S3 bucket with an event notification set up. The trigger of the event is All object create events and it basically runs a lambda function.
Inside the bucket, I have a bunch of folders, one for each operator in our system.
Inside each operator’s folder, there might be a folder called /exports/.
Objective
For objects created within the /exports/ folder (under the operator folder), I do not want to trigger the event.
Is that possible with S3?
>Solution :
No, not supported afaik. You have three options:
-
Use two buckets, one for the dropped items and one for the exports, where each bucket would have a BLAC/ prefix, a CUCC/ prefix etc.
-
Restructure your prefixes within this one bucket to have: import/BLACC/ , import/CUCC/, export/BLACC/, export/CUCC/ and configure the upload trigger on the prefix import/
-
Modify your Lambda function to treat objects with exports/ in their key as a no-op.
