Flat File Parquet

This page shows how to set up and use the Flat File Parquet destination. The Flat File Parquet destination loads data to a Parquet Database destination.

Create a new Flat File Parquet Destination

Follow the steps below to add a new Flat File Parquet destination to Xtract Universal:

1. In the main window of the Designer, navigate to Server > Manage Destinations. The window “Manage Destinations” opens.
   
2. Click [Add] to create a new destination. The window "Destination Details" opens.
   
3. Enter a Name for the destination.
4. Select the destination type Flat File Parquet from the drop-down menu. A list of connection details opens.
5. Fill out the destination details to connect to the destination.
6. Click [OK] to confirm your input.

The destination can now be assigned to extractions.

Destination Details

The destination details define the connection to the destination.

Output directory

Enter the folder path to save the destination flat files in. If the entered folder does not exist, a new folder is created.

Compatibility mode

The following compatibility modes are available:

• Pure
• Spark (does not support the data types used in pure mode, so other data types need to be used)
• BigQuery (formats columns names to be compatible with Google BigQuery, see BigQuery Documentation: Column Names)

Assign the Flat File Parquet Destination to an Extraction

Extractions write data to their assigned destination. Follow the steps below to assign a destination to an extraction:

1. In the main window of the Designer, select an extraction.
2. Click [ Destination]. The window “Destination Settings” opens.
   
3. In the “Destination Settings” window, select a destination from the dropdown list.
   
4. Optional: edit the destination settings.
5. Click [OK] to confirm your input.

When running the extraction, the extracted SAP data is now written to the destination.

Destination Settings

The destination settings only affect the extraction that the destination is assigned to. To open the destination settings, select an extraction in the main window of the Designer and click [ Destination]. The window "Destination Settings" opens.

File Name

Determines the name of the target table. The following options are available:

Append timestamp

Add the timestamp in the UTC format (_YYYY_MM_DD_hh_mm_ss_fff) to the file name of the extraction

Use Script Expressions as Dynamic File Names

Script expressions can be used to generate a dynamic file name. This allows generating file names that are composed of an extraction's properties, e.g. extraction name, SAP source object. This scenario supports script expressions based on .NET and the following XU-specific custom script expressions:

#{Source.Name}#

#{Extraction.ExtractionName}#

#{Extraction.Type}#

#{Extraction.SapObjectName}#

#{Extraction.Timestamp}#

#{Extraction.SapObjectName.TrimStart("/".ToCharArray())}#

#{Extraction.SapObjectName.Replace('/', '_')}#

#{Extraction.Fields["FISCPER"].RangeSelections[0].LowerValue}#

#{Extraction.Fields["FISCPER"].RangeSelections[0].UpperValue}#

#{Extraction.Context}#

#{Extraction.Fields["[NameSelectionFiels]"].Selections[0].Value}#

#{Odp.UpdateMode}#

#{TableExtraction.WhereClause}#

Column Name Style

Defines the style of the column name. Following options are available:

Convert dates

Converts the character-type SAP date (YYYYMMDD, e.g., 19900101) to a special date format (YYYY-MM-DD, e.g., 1990-01-01). Target data uses a real date data-type and not the string data-type to store dates.

Year 0

Converts the SAP date 00000000 to the entered value.

Year 9999

Converts the SAP date 9999XXXX to the entered value.

Invalid values

If an SAP date cannot be converted to a valid date format, the invalid date is converted to the entered value. NULL is supported as a value. When converting the SAP date the two special cases 00000000 and 9999XXXX are checked first.

Existing files

If a flat file by the same name already exists in the target directory, the following actions can be taken:
