Filter related events RRS feed

  • Question

  • I am building an application where we get location events from mobile devices constantly. The SA job I am trying to build, should filter all events that are not close to each other and only output those that are. So, when three devices send a location and two of them are less than 0,1 (absolute) away from each other, only those two devices should be outputted. How can you achieve this in SA?

  • Stream Analytics does not yet provide geospatial functions/operators so it might be hard to implement this scenario today.

    One possible solution is to map your locations to some fixed grid coordinates and do GROUP BY over locations in this grid.
