Hi, This is just a heads up. Szehon and I just make a spec change to include multi-arg transform: https://github.com/apache/iceberg/pull/8579 recently. I am sending this to get input from others who did not review the pr before Iceberg 1.5 release. Any concerns/suggestions are appreciated.
After this change, we are working to get the API/Core and engine changes into the iceberg and more importantly the concrete multi-arg transforms, such as bucketV2 or zorder, etc.
