[jira] [Created] (IMPALA-11544) Support migrating ACID tables to Iceberg tables

Manish Maheshwari created IMPALA-11544:
------------------------------------------

             Summary: Support migrating ACID tables to Iceberg tables
                 Key: IMPALA-11544
                 URL: https://issues.apache.org/jira/browse/IMPALA-11544
             Project: IMPALA
          Issue Type: New Feature
            Reporter: Manish Maheshwari


To extend Impala support for Iceberg, we should support reading Hive ACID tables and re-creating them in the iceberg format. The steps would be 
 # Read ACID table
 # Create iceberg table in V2 format and parquet file format with a temporary name
 # Drop ACID table
 # Rename the iceberg temporary named table to the original table name
 # Collect stats (optionally)
