IcebergTransform

class aws_cdk.aws_s3tables_alpha.IcebergTransform(*args: Any, **kwargs)

Bases: object

(experimental) Iceberg transform values for partition and sort fields.

Stability:: experimental
ExampleMetadata:: infused

Example:

from aws_cdk.aws_s3tables_alpha import IcebergMetadataProperty, IcebergSchemaProperty, SchemaFieldProperty, SchemaFieldProperty, IcebergPartitionSpec, IcebergPartitionField
# Build a table with partition spec (minimal configuration)
partitioned_table = Table(scope, "PartitionedTable",
    table_name="partitioned_table",
    namespace=namespace,
    open_table_format=OpenTableFormat.ICEBERG,
    iceberg_metadata=IcebergMetadataProperty(
        iceberg_schema=IcebergSchemaProperty(
            schema_field_list=[SchemaFieldProperty(name="event_date", type="date", required=True), SchemaFieldProperty(name="event_name", type="string")
            ]
        ),
        iceberg_partition_spec=IcebergPartitionSpec(
            fields=[IcebergPartitionField(
                source_id=1,
                transform=IcebergTransform.IDENTITY,
                name="date_partition"
            )
            ]
        )
    )
)
