IcebergMetadata

The partition specification for the Iceberg table. Partitioning organizes data into separate files based on the values of one or more fields, which can improve query performance by reducing the amount of data scanned. Each partition field applies a transform (such as identity, year, month, or bucket) to a single field.

A map of custom configuration properties for the Iceberg table.

The schema for an Iceberg table. Use this property to define table schemas with primitive types only. For schemas that include nested or complex types such as struct, list, or map, use schemaV2 instead.

The schema for an Iceberg table using the V2 format. Use this property to define table schemas that include nested or complex data types such as struct, list, or map, in addition to primitive types. For schemas with only primitive types, you can use either schema or schemaV2.

The sort order for the Iceberg table. Sort order defines how data is sorted within data files, which can improve query performance by enabling more efficient data skipping and filtering.
