Class DataCatalog

    • Method Detail

      • name

        public final String name()

        The name of the data catalog. The catalog name must be unique for the Amazon Web Services account and can use a maximum of 127 alphanumeric, underscore, at sign, or hyphen characters. The remainder of the length constraint of 256 is reserved for use by Athena.

        Returns:
        The name of the data catalog. The catalog name must be unique for the Amazon Web Services account and can use a maximum of 127 alphanumeric, underscore, at sign, or hyphen characters. The remainder of the length constraint of 256 is reserved for use by Athena.

      • description

        public final String description()

        An optional description of the data catalog.

        Returns:
        An optional description of the data catalog.

      • type

        public final DataCatalogType type()

        The type of data catalog to create: LAMBDA for a federated catalog, HIVE for an external hive metastore, or GLUE for an Glue Data Catalog.

        If the service returns an enum value that is not available in the current SDK version, type will return DataCatalogType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from typeAsString().

        Returns:
        The type of data catalog to create: LAMBDA for a federated catalog, HIVE for an external hive metastore, or GLUE for an Glue Data Catalog.

        DataCatalogType

      • typeAsString

        public final String typeAsString()

        The type of data catalog to create: LAMBDA for a federated catalog, HIVE for an external hive metastore, or GLUE for an Glue Data Catalog.

        If the service returns an enum value that is not available in the current SDK version, type will return DataCatalogType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from typeAsString().

        Returns:
        The type of data catalog to create: LAMBDA for a federated catalog, HIVE for an external hive metastore, or GLUE for an Glue Data Catalog.

        DataCatalogType

      • hasParameters

        public final boolean hasParameters()
        For responses, this returns true if the service returned a value for the Parameters property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • parameters

        public final Map<String,​String> parameters()

        Specifies the Lambda function or functions to use for the data catalog. This is a mapping whose values depend on the catalog type.

        • For the HIVE data catalog type, use the following syntax. The metadata-function parameter is required. The sdk-version parameter is optional and defaults to the currently supported version.

          metadata-function=lambda_arn, sdk-version=version_number

        • For the LAMBDA data catalog type, use one of the following sets of required parameters, but not both.

          • If you have one Lambda function that processes metadata and another for reading the actual data, use the following syntax. Both parameters are required.

            metadata-function=lambda_arn, record-function=lambda_arn

          • If you have a composite Lambda function that processes both metadata and data, use the following syntax to specify your Lambda function.

            function=lambda_arn

        • The GLUE type takes a catalog ID parameter and is required. The catalog_id is the account ID of the Amazon Web Services account to which the Glue catalog belongs.

          catalog-id=catalog_id

          • The GLUE data catalog type also applies to the default AwsDataCatalog that already exists in your account, of which you can have only one and cannot modify.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasParameters() method.

        Returns:

          catalog-id=catalog_id

      • hashCode

        public final int hashCode()
        Overrides:
        hashCode in class Object

      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object

      • getValueForField

        public final <T> Optional<T> getValueForField​(String fieldName,
