Class CreateDataCatalogRequest

    • Method Detail

      • name

        public final String name()

        The name of the data catalog to create. 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.

        For FEDERATED type the catalog name has following considerations and limits:

        • The catalog name allows special characters such as _ , @ , \ , - . These characters are replaced with a hyphen (-) when creating the CFN Stack Name and with an underscore (_) when creating the Lambda Function and Glue Connection Name.

        • The catalog name has a theoretical limit of 128 characters. However, since we use it to create other resources that allow less characters and we prepend a prefix to it, the actual catalog name limit for FEDERATED catalog is 64 - 23 = 41 characters.

        Returns:

      • type

        public final DataCatalogType type()

        The type of data catalog to create: LAMBDA for a federated catalog, GLUE for an Glue Data Catalog, and HIVE for an external Apache Hive metastore. FEDERATED is a federated catalog for which Athena creates the connection and the Lambda function for you based on the parameters that you pass.

        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, GLUE for an Glue Data Catalog, and HIVE for an external Apache Hive metastore. FEDERATED is a federated catalog for which Athena creates the connection and the Lambda function for you based on the parameters that you pass.

      • typeAsString

        public final String typeAsString()

        The type of data catalog to create: LAMBDA for a federated catalog, GLUE for an Glue Data Catalog, and HIVE for an external Apache Hive metastore. FEDERATED is a federated catalog for which Athena creates the connection and the Lambda function for you based on the parameters that you pass.

      • description

        public final String description()

        A description of the data catalog to be created.

        Returns:
        A description of the data catalog to be created.

      • 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 creating 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 Data 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.

        • The FEDERATED data catalog type uses one of the following parameters, but not both. Use connection-arn for an existing Glue connection. Use connection-type and connection-properties to specify the configuration setting for a new connection.

          • connection-arn:<glue_connection_arn_to_reuse>

          • lambda-role-arn (optional): The execution role to use for the Lambda function. If not provided, one is created.

          • connection-type:MYSQL|REDSHIFT|...., connection-properties:"<json_string>"

            For <json_string> , use escaped JSON text, as in the following example.

            "{\"spill_bucket\":\"my_spill\",\"spill_prefix\":\"athena-spill\",\"host\":\"abc12345.snowflakecomputing.com\",\"port\":\"1234\",\"warehouse\":\"DEV_WH\",\"database\":\"TEST\",\"schema\":\"PUBLIC\",\"SecretArn\":\"arn:aws:secretsmanager:ap-south-1:111122223333:secret:snowflake-XHb67j\"}"

        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:
        Specifies the Lambda function or functions to use for creating 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

            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 Data Catalog belongs.

          catalog-id=catalog_id

      • hasTags

        public final boolean hasTags()
        For responses, this returns true if the service returned a value for the Tags 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.

      • tags

        public final List<Tag> tags()

        A list of comma separated tags to add to the data catalog that is created. All the resources that are created by the CreateDataCatalog API operation with FEDERATED type will have the tag federated_athena_datacatalog="true". This includes the CFN Stack, Glue Connection, Athena DataCatalog, and all the resources created as part of the CFN Stack (Lambda Function, IAM policies/roles).

        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 hasTags() method.

      • 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.
