Workflow Writer

KNIME Virtual Nodes version 4.4.0.v202104131306 by KNIME AG, Zurich, Switzerland

Writes a workflow from a port object into a directory or an exported KNIME workflow (.knwf) archive.

Options

Write to
Select a file system to write to. There are four default file system options to choose from:
  • Local File System: Allows you to select a directory from your local system.
  • Relative to: Allows you to choose whether to resolve the path relative to the workflow, mountpoint or node.
  • Mountpoint: Allows you to choose a mountpoint. Whenever this is selected, a new drop-down menu appears to choose from available mountpoints.
  • Custom URL: Uses the standard URL handler providing the ability to read a file from URLs (e.g. file, http or KNIME protocol). Browsing and reading folders as well as several of the options below are disabled when writing to a Custom URL.
It is possible to use other file systems with this node. To this end, you have to enable the file system connection input port of this node by clicking the ... in the bottom left corner of the node's icon and choose Add File System Connection port. Afterwards, you can simply connect the desired connector node to the Workflow Writer node. The file system connection will then be shown in the drop down menu.
File / URL
Enter a valid destination. Depending on the selected file system this is either a path or a URL pointing to a directory.
You can also choose a previously selected file/folder from the drop-down list, or select a destination from the "Browse..." dialog.
Timeout (ms)
When writing to a custom URL, this value determines the maximum amount of time in milliseconds to establish a connection.
Overwrite folder content if exists
This checkbox determines whether to overwrite existing files in the selected destination folder.
Create parent directories if required
If checked, any parents of the destination folder that do not exist yet are created.
Export workflow as knwf archive
If the workflow should be written as .knwf archive instead of a directory.
Open after write
Determines whether the workflow should be opened in KNIME Analytics Platform after it has been written to a local workspace.
Use custom workflow name
If checked, a custom workflow name is used as specified below. Otherwise the original workflow name, as shown above, is used.
