+
+.. spark:function:: spark_partition_id() -> integer
+
+    Returns the current partition id.
+    The framework provides partition id through the configuration 'spark.partition_id'.
+    It ensures deterministic data partitioning and assigns a unique partition id to each task in a deterministic way.
+    Consequently, this function is marked as deterministic, enabling Velox to perform constant folding on it.
