/AWS1/CL_S3TICEBERGMETADATA

Contains details about the metadata for an Iceberg table.

CONSTRUCTOR

IMPORTING

Optional arguments:

io_schema TYPE REF TO /AWS1/CL_S3TICEBERGSCHEMA /AWS1/CL_S3TICEBERGSCHEMA

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.

io_schemav2 TYPE REF TO /AWS1/CL_S3TICEBERGSCHEMAV2 /AWS1/CL_S3TICEBERGSCHEMAV2

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.

io_partitionspec TYPE REF TO /AWS1/CL_S3TICEBERGPARTSPEC /AWS1/CL_S3TICEBERGPARTSPEC

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.

io_writeorder TYPE REF TO /AWS1/CL_S3TICEBERGSORTORDER /AWS1/CL_S3TICEBERGSORTORDER

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.

it_properties TYPE /AWS1/CL_S3TTABLEPROPERTIES_W=>TT_TABLEPROPERTIES TT_TABLEPROPERTIES

A map of custom configuration properties for the Iceberg table.

Queryable Attributes

schema

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.

schemaV2

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.

Accessible with the following methods

Method	Description

partitionSpec

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.
