+### USE_TOJA(boolean_value)
+
+The `boolean_value` parameter can be `TRUE` or `FALSE`. The `USE_TOJA(TRUE)` hint enables the optimizer to convert an `in` condition (containing a sub-query) to join and aggregation operations. Comparatively, the `USE_TOJA(FALSE)` hint disables this feature.
+
+For example, the following query will convert `in (select t2.a from t2) subq` to corresponding join and aggregation operations:
+
+{{< copyable "sql" >}}
+
+```sql
+select /*+ USE_TOJA(TRUE) */ t1.a, t1.b from t1 where t1.a in (select t2.a from t2) subq;

+In addition to this hint, setting the `tidb_opt_insubq_to_join_and_agg` environment variable also controls whether to enable this feature.

 ## Hints for setting operation parameters
 
 A hint for setting operation parameters follows behind **the first** `SELECT`, `UPDATE` or `DELETE` keyword in a SQL statement. A hint of this category modifies the operation parameter of the query to which this hint applies.
