* Minimal persistence stub for Elasticsearch table.

* <p>This class exists solely for backward compatibility with older metadata images
* that contain serialized EsTable entries. It preserves only the persistence fields
* needed for Gson deserialization. All functional ES logic has been moved to
* {@link org.apache.doris.datasource.es.EsExternalTable}.</p>
*
* <p>Internal ES tables are no longer supported. Users should use ES Catalog instead.</p>
