raminqaf opened a new pull request, #28163:
URL: https://github.com/apache/flink/pull/28163
## What is the purpose of the change
The parser already accepted `ALTER MATERIALIZED TABLE t SET ('k' = 'v')`,
but the planner had no converter registered for
`SqlAlterMaterializedTableOptions`. As a result, the statement was rejected at
plan time with `TableException: Unsupported query`.
Add `SqlAlterMaterializedTableOptionsConverter` and register it in
`SqlNodeConverters#registerMaterializedTableConverters`. The converter emits an
`AlterMaterializedTableChangeOperation` with one `TableChange.set(key, value)`
per option provided. Merge with existing options is handled by
`MaterializedTableChangeHandler.setTableOption`, which mirrors the
create-or-alter path established in FLINK-39199.
Planner-level tests cover the success path, single-option summary string,
unknown table, and applying SET to a regular table. A gateway IT test exercises
the end-to-end flow in FULL refresh mode where the change is applied directly
to the catalog. The user-facing docs are updated for the new SET clause.
## Brief change log
