@@ -409,3 +409,26 @@ To solve this issue, explicitly provide the type of the
dynamic parameter using
```
SELECT * FROM druid.foo WHERE dim1 like CONCAT('%', CAST (? AS VARCHAR), '%')
```
+
+Dynamic parameters can also replace arrays, reducing the parsing time.
+
+for example:
+```json
+{
+ "query": "SELECT doubleArrayColumn from druid.table where
ARRAY_CONTAINS(?, doubleArrayColumn)",
+ "parameters": [
+ {"type":"ARRAY", "value":[-25.7, null, 36.85]}
+ ]
+}
+```
+
+Also, an IN filter being supplied with a lot of values, can be replaced by a
dynamic parameter passed inside
[SCALAR_IN_ARRAY](sql-functions.md#scalar_in_array)
+```json
+{
+ "query": "SELECT count(city) from druid.table where SCALAR_IN_ARRAY(city,
?)",
+ "parameters": [
+ {"type":"ARRAY", "value":["Vienna", "Seoul", "San Francisco"]}
+ ]
+}
+```
