The Struct Mask generator applies selected generators to specific StructFields within a StructType in a Spark database.
Link object structure
For the Struct Mask generator, there is a link object for each path expression value to assign a sub-generator to.
The generator does not itself support consistency or differential privacy.
The metadata object is populated from the JsonMaskMetadata object, and includes:
pathExpression, which is the expression that identifies the value to apply the sub-generator to.
The types of values to apply the sub-generator to.
The subGeneratorMetadata object, which identifies and configures the selected sub-generator.
{"schema":"string","table":"string","column":"string""metadata": {"generatorId":"StructMaskGenerator","customValueProcessor":"string"//If custom value processor applied"pathExpression": "string","jsonFilterTypes": [ enum ],"subGeneratorMetadata": {"presetId":"string","generatorId":"string",//Metadata for the selected sub-generator"customValueProcessor":"string",//If custom value processor applied to the sub-generator }}
Example replacement
In the following example replacement for the StructMask generator:
The value at the path expression $.address.city is assigned the Address generator. The generator is configured to produce a city value. Consistency is disabled.
The value at the path expression $.address.zip is also assigned the Address generator. The generator is configured to produce a zip code value. Consistency is disabled.
