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.
