…4517) Followup apache#33610 Refactor the logic of schema cache for external table. Before, the ExternalSchemaCache only caches the schema(which is `List<Column>`) of the table. But actually, some other objects are also being refreshed when schema cache refreshing, such as `partition columns`, etc. So This PR mainly changes: 1. Add a new class `SchemaCacheValue` as a parent class for all kinds of cache value in ExternalSchemaCache 2. It contains `List<Column>` basically, and sub class can extend from it to add more cached objects. 3. Move all cached objects into `SchemaCacheValue`, so that they will be refreshed along with schema together. Additional: 1. Remove unused warn log in AcceptListener.java 2. Fix unclear error msg if trino connector's table does not exist.
