Question:
We’re trying to confirm if when there is a PUT event on our bucket that is subscribed to SNS, is it possible for S3 to send multiple records? Here is the message format, notice Records is an array.

Currently, all S3 event notifications have a single event per notification message. We might include multiple records as we add new event types in the future. This is also a message format that is shared across other AWS services, and other services can include multiple records.
