software.amazon.awssdk.services.athena.model.DataCatalog
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<DataCatalog.Builder,DataCatalog>
@Generated("software.amazon.awssdk:codegen") public final class DataCatalog extends Object implements SdkPojo, Serializable, ToCopyableBuilder<DataCatalog.Builder,DataCatalog>

Contains information about a data catalog in an Amazon Web Services account.

In the Athena console, data catalogs are listed as "data sources" on the Data sources page under the Data source name column.

  • Method Details

    • 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.

    • 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.

    • 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.

        • Queries that specify a Glue Data Catalog other than the default AwsDataCatalog must be run on Athena engine version 2.

      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:

    • toBuilder

      public DataCatalog.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<DataCatalog.Builder,DataCatalog>
      Returns:
      a builder for type T

    • builder

      public static DataCatalog.Builder builder()

    • serializableBuilderClass

      public static Class<? extends DataCatalog.Builder> serializableBuilderClass()

    • hashCode

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

    • equals

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

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • 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, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
