Glue.Paginator.GetClassifiers¶paginator = client.get_paginator('get_classifiers')
paginate(**kwargs)¶Creates an iterator that will paginate through responses from Glue.Client.get_classifiers().

Request Syntax
response_iterator = paginator.paginate(
PaginationConfig={
'MaxItems': 123,
'PageSize': 123,
'StartingToken': 'string'
}
)
A dictionary that provides parameters to control pagination.
The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.
The size of each page.
A token to specify where to start paginating. This is the NextToken from a previous response.

Response Structure
The requested list of classifier objects.
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 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.
A classifier that uses grok .
The name of the classifier.
An identifier of the data format that the classifier matches, such as Twitter, JSON, Omniture logs, and so on.
The time that this classifier was registered.
The time that this classifier was last updated.
The version of this classifier.
The grok pattern applied to a data store by this classifier. For more information, see built-in patterns in Writing Custom Classifiers.
Optional custom grok patterns defined by this classifier. For more information, see custom patterns in Writing Custom Classifiers.
A classifier for XML content.
The name of the classifier.
An identifier of the data format that the classifier matches.
The time that this classifier was registered.
The time that this classifier was last updated.
The version of this classifier.
The XML tag designating the element that contains each record in an XML document being parsed. This can't identify a self-closing element (closed by /> ). An empty row element that contains only attributes can be parsed as long as it ends with a closing tag (for example, <row item_a="A" item_b="B"></row> is okay, but <row item_a="A" item_b="B" /> is not).
A classifier for JSON content.
The name of the classifier.
The time that this classifier was registered.
The time that this classifier was last updated.
The version of this classifier.
A JsonPath string defining the JSON data for the classifier to classify. Glue supports a subset of JsonPath, as described in Writing JsonPath Custom Classifiers.
A classifier for comma-separated values (CSV).
The name of the classifier.
The time that this classifier was registered.
The time that this classifier was last updated.
The version of this classifier.
A custom symbol to denote what separates each column entry in the row.
A custom symbol to denote what combines content into a single column value. It must be different from the column delimiter.
Indicates whether the CSV file contains a header.
A list of strings representing column names.
Specifies not to trim values before identifying the type of column values. The default value is true .
Enables the processing of files that contain only one column.
Enables the custom datatype to be configured.
A list of custom datatypes including "BINARY", "BOOLEAN", "DATE", "DECIMAL", "DOUBLE", "FLOAT", "INT", "LONG", "SHORT", "STRING", "TIMESTAMP".
