Study Notes
File Iterator Component
- The File Iterator component allows users to loop over matching files in a remote file system.
- It searches for files in various remote file systems, running its attached component once for each file found.
- Filenames and path names are mapped into environment variables, which can then be referenced from the attached component(s).
Component Properties
- Name: A human-readable name for the component.
- Input Data Type: Select the remote file system to search, including Azure Blob Storage, Cloud Storage, FTP, HDFS, S3, SFTP, and Windows Fileshare.
- Input Data URL: Input the URL, including the full path and file name followed by a forward slash, that will point to the files to download to the selected staging area.
Iteration Properties
- Record Values In Task History: Choose whether to record iteration values in the Matillion ETL Task History. Default setting is Yes.
- Stop On Condition: Select Yes to stop the iteration based on a condition specified in the Condition property. Default setting is No.
- Mode: Select the method of creating the condition, either Simple or Advanced.
- Condition (Simple mode): Specify an Input Variable, Qualifier, Comparator, and Value using drop-down menus and text fields.
- Condition (Advanced mode): Manually write the condition in the editor using JavaScript.
- Combine Conditions: Use the defined conditions in combination with one another according to either And or Or.
Variable Exports
- Iteration Attempted: The number of iterations that this component attempts to reach (Max Iterations parameter).
- Iteration Generated: The number of iterations that have been initiated.
- Iteration Successful: The number of iterations successfully performed.
Concurrency Properties
- Concurrency: Select whether iterations run concurrently or sequentially. Default setting is Sequential.
- Break on Failure: Select whether to attempt to run the attached component for each iteration, regardless of success or failure. Default setting is No.
File Attributes
- Variables: An existing environment variable to hold the given value of the Path Selection.
- File Attribute: For each matched file, the target variable can be populated with the Base Path, the Subfolder, the Filename, or the date of when the file was Last Modified.
