GoogleCloudStorageConnector

Connects to Google Cloud Storage to manage files and folders.

Jump to Configuration

Typical Uses

  • Managing datasets on Google Cloud Storage by uploading, downloading, and deleting files and folders
  • Transferring file contents into or out of an attribute in FME
  • Retrieving file and folder names, paths, links and other information from Google Cloud Storage to use elsewhere in a workspace

How does it work?

The GoogleCloudStorageConnector uses your Google credentials to perform various management tasks on Google Cloud Storage:

Action Task

Delete

Delete files and folders.

Download

Download a file or folder to an attribute, file, or folder.

List

List the item details for the contents of a folder.

Upload

Upload a file, folder, or the contents of an attribute.

Once valid account credentials have been provided, you may browse to available content for the selected Action.

Usage Notes

  • This transformer cannot move or copy files between different locations. Consider using multiple connectors for these tasks, by downloading files/folders and re-uploading them to a new location.

  • The FeatureReader can access Google Cloud Storage directly but does not download a local copy of the dataset.

Configuration

Input Ports

This transformer accepts any feature.

Output Ports

Features with added attributes, as specified in parameters and according to Action:

Action Output

Delete

Input feature unchanged.

Download

Input feature with details about the downloaded item.

List

Multiple features, one for each item in the specified location, with details about the items.

Upload

Input feature with details about the uploaded item.

Input features are output here unmodified, in addition to any other output locations (Output or <Rejected>).

Features that cause the operation to fail are output through this port. An fme_rejection_code attribute describing the category of the error will be added, along with a more descriptive fme_rejection_message which contains more specific details as to the reason for the failure.

If an Input feature already has a value for fme_rejection_code, this value will be removed.

Rejected Feature Handling: can be set to either terminate the translation or continue running when it encounters a rejected feature. This setting is available both as a default FME option and as a workspace parameter.

Parameters

Credential Source

Select the type of credentials to use:

  • Web Connection: (Recommended) Use a Google Cloud Storage web connection.
  • Anonymous: Access public buckets without authenticating.
  • Service Account Key File: Use credentials already configured on the system, in the key file specified in the environment variable GOOGLE_APPLICATION_CREDENTIALS.

Account

When Credential Source is Web Connection, select or create a Web Connection connecting to a Google Cloud StorageWeb Service.

See Using Web Connections.

Project ID

When Credential Source is Web Connection, specify the Google Cloud project id.

Action

Select an operation to perform. Choices include:

  • Delete
  • Download
  • List
  • Upload

Delete Options

Bucket

Specify the bucket the file or folder is in.

Path

Provide the full path of a file or folder on Google Cloud Storage to delete.

Output Attributes

No attributes are added for this Action.

Download Options

Bucket

Specify the bucket the file or folder is in.

Path

Provide the full path of a file or folder on Google Cloud Storage to download.

  • Folder: The downloaded folder object will be stored in the specified folder.

Download to Attribute

When Download as is Attribute, specify the attribute to contain the contents of the downloaded item.

Encoding

FME will attempt to convert the attribute's contents to a UTF-8 string. If this fails, the attribute's contents will be created as raw binary. To ensure that the original bytes are always preserved and never converted to UTF-8, use Download as >File instead.

Response Body Encoding

When Download as is Attribute, select an encoding method.

Options include various character set encodings which ensure the output is in a human-readable form.

If Auto Detect from HTTP Header is specified but there is no encoding in the Content-Type metadata associated with the data, the output will be returned as raw bytes.

Download to Folder

When Download as is File or Folder, specify the path to the folder that will store the downloaded item.

If File Exists

When Download as is File or Folder, select a method for handling existing files:

  • Reject: Leave the existing file intact and output the feature via the <Rejected> port.

Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Text Editor

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

Arithmetic Editor

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Parameter Condition Definition Dialog

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.

String Functions

These functions manipulate and format strings.

Special Characters

 A set of control characters is available in the Text Editor.

Math Functions

Math functions are available in both editors.
Date/Time Functions Date and time functions are available in the Text Editor.

Math Operators

These operators are available in the Arithmetic Editor.

FME Feature Functions

These return primarily feature-specific values.

FME Parameters

FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters Create your own editable parameters.

Table Tools

Transformers with table-style parameters have additional tools for populating and manipulating values.

Row Reordering

Enabled once you have clicked on a row item. Choices include:

  • Add a row
  • Remove a row
  • Move current row up one
  • Move current row down one
  • Move current row to top
  • Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

  • Cut a row - delete and copy to clipboard
  • Copy a row to the clipboard
  • Paste a row from the clipboard

Cut, copy, and paste may be used within a transformer, or between transformers.

Filter

Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output.

Import

Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.

Reset/Refresh

Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers.

Note: Not all tools are available in all transformers.

For more information, see Transformer Parameter Menu Options.
