@Generated(value="software.amazon.awssdk:codegen")
public class Classifier
extends Object
implements StructuredPojo, ToCopyableBuilder<Classifier.Builder,Classifier>

Classifiers are written in Python and triggered during a crawl task. You can write your own classifiers to best categorize your data sources and specify the appropriate schemas to use for them. A classifier checks whether a given file is in a format it can handle, and if it is, the classifier creates a schema in the form of a StructType object that matches that data format.

A classifier can be either a grok classifier or an XML classifier, specified in one or the other field of the Classifier object.
