   ### Query engine
   
   Flink
   
   ### Question
   
   Does iceberg support the Flink materialized tables: 
https://nightlies.apache.org/flink/flink-docs-release-1.20/docs/dev/table/materialized-table/overview/.
   
   I am creating a materialized table in iceberg catalog, and I got an 
exception:
   pyflink.util.exceptions.TableException: 
org.apache.flink.table.api.TableException: Could not execute CreateTable in 
path `iceberg`.`db_click_stream`.`agg_user_page`

   From the code, it seems iceberg only accept the ResolvedCatalogTable, it not 
recognize the ResolvedCatalogMaterializedTable.
   
   Is this because my usage is inappropriate, or because Iceberg has not yet 
supported this feature?
