Problem: After the re-design of `UPDATE` and `DELETE` in MDEV-28883, the call to find select handler is missing. This prevents the server from handring over multi-update/multi-delete queries to storage engines capable of executng such queries on their own (e.g., ColumnStore). MDEV-32382 introduced a check in `find_select_handler_inner` function, that blocked pushdown of queries involving CTEs, without checking if the storage engine is capable of handling such queries. Fix: Add a call to find the select handler for the engine involved in the multi-update/multi-delete query, allowing the storage engines to execute such queries. Fix the `find_select_handler_inner` function by allowing the storage engine's create_select functions to decide the pushdown of queries involving CTEs. |
