Description
Task Overview:
Currently, Fluss does not allow users to alter Lake table properties (i.e., properties prefixed with the datalake format name, such as paimon.*) via ALTER TABLE ... SET (...) statements. Any attempt to modify such properties results in an InvalidConfigException.
Problem Statement:
When a user attempts to update Lake-specific table properties, such as partition configuration, the following error is thrown:
ALTER TABLE my_catalog.my_database.my_lake_table SET (
'paimon.partition.timestamp-formatter' = 'yyyyMMdd',
'paimon.partition.timestamp-pattern' = '$ds'
);Caused by: org.apache.fluss.exception.InvalidConfigException:
Property 'paimon.partition.timestamp-pattern' is not supported to alter which is for datalake table.
This blanket restriction prevents users from updating valid and necessary Lake table configurations after table creation, such as:
paimon.partition.timestamp-formatterpaimon.partition.timestamp-pattern
Purpose:
Users need the ability to adjust Lake table properties post-creation without having to drop and recreate tables, which is disruptive in production environments.
