All Implemented Interfaces:
Serializable, HasDisplayData
public abstract class DLPDeidentifyText extends PTransform<PCollection<KV<String,String>>,PCollection<KV<String,com.google.privacy.dlp.v2.DeidentifyContentResponse>>>
A PTransform connecting to Cloud DLP (https://cloud.google.com/dlp/docs/libraries) and deidentifying text according to provided settings. The transform supports both columnar delimited input data (eg. CSV) and unstructured input.

If the headerColumns property is set and a sideinput with table headers is added to the PTransform, delimiter also should be set, else the results will be incorrect. If headerColumns is neither set nor passed as side input, input is assumed to be unstructured.

Either deidentifyTemplateName (String) or deidentifyConfig DeidentifyConfig need to be set. inspectTemplateName and inspectConfig (InspectConfig are optional.

Batch size defines how big are batches sent to DLP at once in bytes.

The transform consumes KV of Strings (assumed to be filename as key and contents as value) and outputs KV of String (eg. filename) and DeidentifyContentResponse, which will contain Table of results for the user to consume.
