Partition specification for Iceberg table.

Contains the complete partitioning configuration for a table, including all partition fields. Use this to define multi-level partitioning (e.g., partition by date, then by region).

Example

// Build a table with partition spec (minimal configuration)
const partitionedTable = new Table(scope, 'PartitionedTable', {
    tableName: 'partitioned_table',
    namespace: namespace,
    openTableFormat: OpenTableFormat.ICEBERG,
    icebergMetadata: {
        icebergSchema: {
            schemaFieldList: [
                { name: 'event_date', type: 'date', required: true },
                { name: 'event_name', type: 'string' },
            ],
        },
        icebergPartitionSpec: {
            fields: [
                {
                    sourceId: 1,
                    transform: IcebergTransform.IDENTITY,
                    name: 'date_partition',
                },
            ],
        },
    },
});
