Amazon S3 Connector

Amazon S3 Filehandling version 4.3.2.v202103021015 by KNIME AG, Zurich, Switzerland

This node configures the connection information that will be used to connect to Amazon S3. Using this connection the other KNIME remote file handling nodes such as Excel Reader and Excel Writer can download and upload files from and to Amazon S3.

For further documentation please take a look at the AWS Documentation.

Path syntax: Paths for Amazon S3 are specified with a UNIX-like syntax, /mybucket/myfolder/myfile. An absolute for S3 consists of:

  1. A leading slash ("/").
  2. Followed by the name of a bucket ("mybucket" in the above example), followed by a slash.
  3. Followed by the name of an object within the bucket ("myfolder/myfile" in the above example).

Options

Settings

Working directory
Specifies the working directory using the path syntax explained above. The working directory must be specified as an absolute path. A working directory allows downstream nodes to access files/folders using relative paths, i.e. paths that do not have a leading slash. If not specified, the default working directory is "/".
Normalize paths
Determines if the path normalization should be applied. Path normalization eliminates redundant components of a path like, e.g. /a/../b/./c" can be normalized to "/b/c". When these redundant components like "../" or "." are part of an existing object, then normalization must be deactivated in order to access them properly.

Advanced

Read/write timeout in seconds
The socket read/write timeout. For further details see the S3 documentation.
Server-side encryption (SSE)
If selected, all data written to S3 will be encrypted with Server-side encryption (SSE). Both SSE-S3 and SSE-KMS are supported.
Use default AWS managed key
If SSE-KMS is selected as the SSE method, then this option specifies whether or not to encrypt data with the default AWS managed CMK.
KMS key id
If SSE-KMS is selected as the SSE method and the default AWS managed CMK should not be used, then this option allows to choose the KMS key with which to encrypt data written to S3. Click on List keys to fetch the list of available keys (requires permissions kms:ListKeys, kms:DescribeKey and optionally kms:ListAliases).
