ALTER TABLE SET TBLPROPERTIES

Adds properties to an Iceberg table and sets their assigned values.

In accordance with Iceberg specifications, table properties are stored in the Iceberg table metadata file rather than in Amazon Glue. Athena does not accept custom table properties. Refer to the Specify table properties section for allowed key-value pairs. You can also use ALTER TABLE SET TBLPROPERTIES and ALTER TABLE UNSET TBLPROPERTIES to set or remove the write.data.path and write.object-storage.path Iceberg table properties. If you would like Athena to support a specific open source table configuration property, send feedback to athena-feedback@amazon.com.

ALTER TABLE iceberg_table SET TBLPROPERTIES (
