AWS S3¶

The AWS S3 node establishes a connection to AWS S3 for file downloading.

Only 1 file can be downloaded using the AWS S3 node. Nodes under the Action node type such as the File node can subsequently be used to read/write to the file. If you need to download files from AWS S3 according to an interval, it is recommended to use S3 File node.
