AWS Glue
Web API Reference (API Version 2017-03-31)


Classifiers are triggered during a crawl task. 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.

You can use the standard classifiers that AWS Glue supplies, 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.
