Parameters:

• GrokClassifier (dict) –

  A GrokClassifier object with updated fields.

  • Name (string) – [REQUIRED]

    The name of the GrokClassifier.

  • Classification (string) –

    An identifier of the data format that the classifier matches, such as Twitter, JSON, Omniture logs, Amazon CloudWatch Logs, and so on.

  • GrokPattern (string) –

    The grok pattern used by this classifier.

  • CustomPatterns (string) –

    Optional custom grok patterns used by this classifier.

• XMLClassifier (dict) –

  An XMLClassifier object with updated fields.

  • Name (string) – [REQUIRED]

    The name of the classifier.

  • Classification (string) –

    An identifier of the data format that the classifier matches.

  • RowTag (string) –

    The XML tag designating the element that contains each record in an XML document being parsed. This cannot 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).

• JsonClassifier (dict) –

  A JsonClassifier object with updated fields.

  • Name (string) – [REQUIRED]

    The name of the classifier.

  • JsonPath (string) –

    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.

• CsvClassifier (dict) –

  A CsvClassifier object with updated fields.

  • Name (string) – [REQUIRED]

    The name of the classifier.

  • Delimiter (string) –

    A custom symbol to denote what separates each column entry in the row.

  • QuoteSymbol (string) –

    A custom symbol to denote what combines content into a single column value. It must be different from the column delimiter.

  • ContainsHeader (string) –

    Indicates whether the CSV file contains a header.

  • Header (list) –

    A list of strings representing column names.

    • (string) –

  • DisableValueTrimming (boolean) –

    Specifies not to trim values before identifying the type of column values. The default value is true.

  • AllowSingleColumn (boolean) –

    Enables the processing of files that contain only one column.

  • CustomDatatypeConfigured (boolean) –

    Specifies the configuration of custom datatypes.

  • CustomDatatypes (list) –

    Specifies a list of supported custom datatypes.

    • (string) –

Return type:

dict
