Create table as select feature
You can create an Iceberg table based on an existing Hive or Impala table.
The create table as select (CTAS) query can optionally include a partitioning spec for the table being created.
Hive examples
CREATE EXTERNAL TABLE ctas STORED BY ICEBERG AS SELECT i, t, j FROM ice_1;
Impala examples
CREATE TABLE ctas STORED BY ICEBERG AS SELECT i, b FROM ice_11;
