+    [7] Prediction Orchestrator – to – Forecasting Methods Events Format
+
+    This event is used by the Prediction Orchestrator to instruct a forecasting method to start producing predicted values for a selection of metrics.
+
+
+    * Topic: start_forecasting.[forecasting_method]
+    * Each component that implements a specific forecasting method it should subscribe to its relevant topic (e.g. the ES-Hybrid component should subscribe to start_forecasting.eshybrid topic)
+    * We consider that each forecasting method should publish a static (but configurable) number m of  predicted values (under the same timestamp) for time points into the future. These time points into the future are relevant to the reconfiguration time that it is needed (and can also be updated).
+        * For example if we configure m=5 predictions into the future and the reconfiguration time needed is TR=10 minutes, then at t0 a forecasting method publishes 5 events with the same timestamp and prediction times t0+10, t0+20, t0+30, t0+40, t0+50.
