Modifying an Iceberg Table

Currently, the following operations can be performed on Iceberg tables: modifying table attributes and restoring default values of table attributes. For details about the syntax, see ALTER TABLE.

Modifying Table Attributes

You can modify the attribute values of a table using the SET/UNSET TABLEPROPERTIES capability of the ALTER TABLE syntax.

Example:

    
         ALTER TABLE iceberg_ext SET TABLEPROPERTIES ('write.metadata.delete-after-commit.enabled' = 'false');
ALTER TABLE iceberg_ext UNSET TABLEPROPERTIES ('write.metadata.delete-after-commit.enabled');
