     To explicitly instruct the optimizer to push index lookups down to TiKV for a specific table, you can use the [`INDEX_LOOKUP_PUSHDOWN(t1_name, idx1_name [, idx2_name ...])`](https://docs.pingcap.com/tidb/v8.5/optimizer-hints#index_lookup_pushdownt1_name-idx1_name--idx2_name--new-in-v855) hint. It is recommended to combine this hint with the table's AFFINITY attribute. For example, set `AFFINITY="table"` for regular tables and `AFFINITY="partition"` for partitioned tables.
