Amazon S3 File Picker (legacy)

KNIME Amazon Cloud Connectors version 4.4.0.v202104131255 by KNIME AG, Zurich, Switzerland

This is a legacy file handling node and will be replaced in the foreseeable future. For further information about the new file handling framework see the File Handling Guide.

This node reads the Amazon S3 connection and generates a pre-signed URL that points to an Amazon S3 object. The URL is only valid for a specific period of time. Upon expiry, the URL will no longer remain active and an attempt to access the URL once it has expired will generate an error. It is not needed to set the permission to access the S3 object to public. Using the generated pre-signed URL, any KNIME reader can be utilized to directly read the S3 object without having to fetch the object locally first.

URLs can be signed for a maximum of 7 days.

The Amazon S3 object, from which the pre-signed URL should be created.

On Date
