+### Streaming Algorithm Priority
+If you are experiencing slower algorithm allocation in streaming pipelines, these algorithms have a special priority setting. To use it, you need to set the `stateType` in your algorithm spec to either **stateless** or **stateful**.
+
+When set:  
+- **Stateful** - A Kubernetes Job is created and launched immediately. These jobs are given the highest priority and start execution right away.  
+- **Stateless** - Jobs are launched after all stateful ones.  
+
+Example for algorithm spec:
+```json
+{
+    "name": "stateful-alg",
+    "cpu": 1,
+    "gpu": 0,
+    "mem": "256Mi",
+    "stateType": "stateful",
+    "algorithmImage": "hkube/algorithm-example-python"
