Description

INSERT INTO Iceberg tables that use partition transforms. Partition transforms are functions that calculate partition data from row data.

There are the following partition transforms in Iceberg:

https://iceberg.apache.org/spec/#partition-transforms

• IDENTITY
• BUCKET
• TRUNCATE
• YEAR
• MONTH
• DAY
• HOUR

INSERT INTO identity-partitioned Iceberg tables are already supported.

We need to add support for the rest.
