+## <a id="Parallel_sort_parameter">Parallel Sort Parameter</a>
+The following parameter enables you to activate or deactivate full parallel sort for order-by operations.
+
+When full parallel sort is inactive (`false`), each existing data partition is sorted (in parallel),
+and then all data partitions are merged into a single node.
+
+When full parallel sort is active (`true`), the data is first sampled, and then repartitioned
+so that each partition contains data that is greater than the previous partition.
+The data in each partition is then sorted (in parallel),
+but the sorted partitions are not merged into a single node.
+
+* **compiler.sort.parallel**: A boolean specifying whether full parallel sort is active (`true`) or inactive (`false`).
+  The default value is `true`.
+
+##### Example
+
+    SET `compiler.sort.parallel` "true";
+
+    SELECT VALUE user
+    FROM GleambookUsers AS user
+    ORDER BY ARRAY_LENGTH(user.friendIds) DESC;
