Suppose you have a collection of anonymous telemetry data points for a given road segment, with each telemetry point containing information about its GPS location, heading and speed.
Blue Dot = Anonymous Telemetry Data Point
Red Line = Non centered road segment
How would you calculate/interpolate/extrapolate the width of the road segments in each direction?
Further, given the above solution for calculating the road width in both directions, describe how you would scale your solution to 200,000 road segments.
2. VEHICLE DATA QUERY
Suppose you have an unsorted CSV file of vehicle telemetry data. The list contains ~10M vehicle IDs and coordinates.
Write a public method that will take in a bounding box of coordinates and return the vehicle IDs that lie within.
Describe the modifications you would need to make, in order to support a real time stream of the same information.
3. HIGH VOLUME DATA INGESTION
How would you design/architect a system to 1 ingest billion vehicle telemetry points per day into object storage? Discuss your approach and provide a diagram.
4. LARGE FILE TRANSFER
How you would design/architect a solution to transfer large datasets (think PBs worth of 50-100GB files) between distant network locations (think Israel and US) and/or systems that don't play well together? Discuss your approach and provide a diagram.
