I am working with a geofence of points, each geofence has a category/name of ORDER_ID/METER_ID.
I am processing incoming events which contain ORDER_IDs which match a geofence. I want to use Union to grab all of the geometeries related to that events ORDER_ID and combine them for further processing.
I am trying to use Regex to grab the ORDER_ID out of the incoming event and use the events ORDER_ID to match to Fences this is my current regex:
but it does not seem to work.
However if I manually enter an order id into the union processor, say 123456/.* then it behaves as desired.
I am wondering if I am doing something wrong here, or if Unions cannot use fields in their regular expressions? I cannot find anything one way or the other in any of the documentation.
If it is not possible, what might be a way to specify geofences on an event by event basis?
