TDE Exporter exports tables from KBC Storage into the TDE file format (Tableau Data Extract). This component is normally a part of the Tableau Writer, but it can also be used as a standalone component.
Users can run a TDE exporter job as any other KBC component or register it as an orchestration task. After the exporter finishes, the resulting TDE files will be available in the Storage — File uploads section where you can download them via UI or API.
To run the TDE exporter with a stored configuration, first

See below for the required configuration contents.
This call will give you the ID of the newly created configuration (for instance,
Then create a job with the specified configuration:
You can specify the entire configuration in the API call. The JSON configuration conforms

in.c-main.old-table in the above example). Object properties
are names of the table columns; each must have the

supported column types:
Data for these data types can be specified in the format used in the strptime function. The format is specified as part of the column’s type definition. For example:
If no format is specified, the following default formats are used:
