Class S3GlueParquetTarget

    • Method Detail

      • name

        public final String name()

        The name of the data target.

        Returns:
        The name of the data target.
      • hasInputs

        public final boolean hasInputs()
        For responses, this returns true if the service returned a value for the Inputs 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.
      • inputs

        public final List<String> inputs()

        The nodes that are inputs to the data target.

        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 hasInputs() method.

        Returns:
        The nodes that are inputs to the data target.
      • hasPartitionKeys

        public final boolean hasPartitionKeys()
        For responses, this returns true if the service returned a value for the PartitionKeys 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.
      • partitionKeys

        public final List<List<String>> partitionKeys()

        Specifies native partitioning using a sequence of keys.

        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 hasPartitionKeys() method.

        Returns:
        Specifies native partitioning using a sequence of keys.
      • path

        public final String path()

        A single Amazon S3 path to write to.

        Returns:
        A single Amazon S3 path to write to.
      • compression

        public final ParquetCompressionType compression()

        Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").

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

        Returns:
        Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").
        See Also:
        ParquetCompressionType
      • compressionAsString

        public final String compressionAsString()

        Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").

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

        Returns:
        Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").

      • schemaChangePolicy

        public final DirectSchemaChangePolicy schemaChangePolicy()

        A policy that specifies update behavior for the crawler.

        Returns:
        A policy that specifies update behavior for the crawler.
      • 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,
                                                      Class<T> clazz)
