[−][src]Struct rusoto_glue::Classifier
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.
Fields
csv_classifier: Option<CsvClassifier>
A classifier for comma-separated values (CSV).
grok_classifier: Option<GrokClassifier>
A classifier that uses grok
.
json_classifier: Option<JsonClassifier>
A classifier for JSON content.
xml_classifier: Option<XMLClassifier>
A classifier for XML content.
