Classifier class
Classifiers are triggered during a crawl task. A classifier checks whether a
given file is in a format it can handle. If it is, the classifier creates a
schema in the form of a StructType object that matches that
data format.
You can use the standard classifiers that AWS Glue provides, or you can
write your own classifiers to best categorize your data sources and specify
the appropriate schemas to use for them. A classifier can be a
grok classifier, an XML classifier, a
JSON classifier, or a custom CSV classifier, as
specified in one of the fields in the Classifier object.
