Direct Access Archive , or daa file , is a proprietary file format for disk image files which supports advanced features such as compression, password protection, and splitting to multiple volumes.
Advantages of DAA file format:. Simply put, file extensions are the characters after the dot in the file name, so for example filename. Learn more from Preserve metadata. When you're transforming data in mapping data flows, you can read and write files from Azure Data Lake Storage Gen2 in the following formats:. Format specific settings are located in the documentation for that format.
For more information, see Source transformation in mapping data flow and Sink transformation in mapping data flow. In the source transformation, you can read from a container, folder, or individual file in Azure Data Lake Storage Gen2. The Source options tab lets you manage how the files get read. Wildcard path: Using a wildcard pattern will instruct ADF to loop through each matching folder and file in a single Source transformation.
This is an effective way to process multiple files within a single flow. From your source container, choose a series of files that match a pattern. Only container can be specified in the dataset.
Your wildcard path must therefore also include your folder path from the root folder. First, set a wildcard to include all paths that are the partitioned folders plus the leaf files that you wish to read. Use the Partition Root Path setting to define what the top level of the folder structure is. When you view the contents of your data via a data preview, you'll see that ADF will add the resolved partitions found in each of your folder levels. List of files: This is a file set.
Create a text file that includes a list of relative path files to process. Point to this text file. Column to store file name: Store the name of the source file in a column in your data. Enter a new column name here to store the file name string. After completion: Choose to do nothing with the source file after the data flow runs, delete the source file, or move the source file. The paths for the move are relative. To move source files to another location post-processing, first select "Move" for file operation.
Then, set the "from" directory. If you're not using any wildcards for your path, then the "from" setting will be the same folder as your source folder. File operations run only when you start the data flow from a pipeline run a pipeline debug or execution run that uses the Execute Data Flow activity in a pipeline. File operations do not run in Data Flow debug mode. Filter by last modified: You can filter which files you process by specifying a date range of when they were last modified.
All date-times are in UTC. Enable change data capture Preview : If true, you will get new or changed files only from the last run. Initial load of full snapshot data will always be gotten in the first run, followed by capturing new or changed files only in next runs. For more details, see Change data capture preview.
In the sink transformation, you can write to either a container or folder in Azure Data Lake Storage Gen2. Clear the folder: Determines whether or not the destination folder gets cleared before the data is written. File name option: Determines how the destination files are named in the destination folder. The file name options are:. You can optionally set the umask for files using POSIX read, write, execute flags for owner, user and group. The following commands are supported:.
To learn details about the properties, check Lookup activity. To learn details about the properties, check GetMetadata activity. To learn details about the properties, check Delete activity. The following models are still supported as-is for backward compatibility. You are suggested to use the new model mentioned in above sections going forward, and the ADF authoring UI has switched to generating the new model. To copy all files under a folder, specify folderPath only.
To copy a single file with a given name, specify folderPath with a folder part and fileName with a file name. To copy a subset of files under a folder, specify folderPath with a folder part and fileName with a wildcard filter.
Azure Data Factory can get new or changed files only from Azure Data Lake Storage Gen2 by enabling Enable change data capture Preview in the mapping data flow source transformation. With this connector option, you can read new or updated files only and apply transformations before loading transformed data into destination datasets of your choice. Make sure you keep the pipeline and activity name unchanged, so that the checkpoint can always be recorded from the last run to get changes from there.
If you change your pipeline name or activity name, the checkpoint will be reset, and you will start from the beginning in the next run. When you debug the pipeline, the Enable change data capture Preview works as well.
Be aware that the checkpoint will be reset when you refresh your browser during the debug run. After you are satisfied with the result from debug run, you can publish and trigger the pipeline. It will always start from the beginning regardless of the previous checkpoint recorded by debug run. In the monitoring section, you always have the chance to rerun a pipeline.
When you are doing so, the changes are always gotten from the checkpoint record in your selected pipeline run. For a list of data stores supported as sources and sinks by the copy activity, see Supported data stores.
