File resources

A file resource is any type of file that is needed locally on a flow runtime by an active running flow. Examples of file resources include the following:

• Machine learning (ML) models that are loaded into an ML framework in a PythonBridge module

• A CSV file accessed by the CSV Reader module

CONNECT flows makes no assumptions on the format or content of resource files. It only ensures that these files are downloaded to the flow runtime for the flow that reference these resources.

Filename guidelines

File resource names must adhere to the following filename guidelines:

• Use a local filename that contains a path.

• The local filename can contain alphanumeric characters and the following characters: ‘.’, ‘_’, ‘-’ and ‘/’.

  Note: A valid filename is ‘a/b/c/test.csv’. An invalid filename is ‘a/b/c/test 2.csv’.

• When accessing a file from within a module in a flow, use a base path of ‘data/Flowresources/’. For example, the previous file example should be referenced as ‘data/Flowresources/a/b/c/test.csv’.

Use the Copy button on the Resources panel to copy the full path of the file resource name.
