Iceberg considerations

When working with Iceberg, keep these points in mind to ensure proper configuration and reliable data handling:

• Ensure Iceberg tables exist at the time of mapping.
• Avoid using tables with the property OBJECT_STORE_ENABLED.
• Prevent direct writes to tables that define Iceberg partitions.
• Supports mapping for standard mirror, audit, and adaptive apply.
• Exclude row-level and subscription exits from Iceberg mappings.
• Disallow MBCS mappings, since Parquet requires UTF-8 strings.
• Define a key in Standard Apply mappings; otherwise, a default key is chosen.
• Utilize the Iceberg Version 2 specification in the client library.
• Write all data files in Parquet format, with Standard and Adaptive Apply mappings using equality deletes.
• Apply data with eventual consistency and guarantee delivery.
