I suspect there is an error in this query: WITH streaming_data AS ( SELECT timestamp, TIMESTAMP_TRUNC(timestamp, HOUR, 'UTC') AS hour, TIMESTAMP_TRUNC(timestamp, MINUTE, 'UTC') AS minute, TIMESTAMP_TRUNC(timestamp, SECOND, 'UTC') AS second, ride_id, latitude, longitude, meter_reading, ride_status, passenger_count FROM taxirides.realtime ORDER BY timestamp DESC LIMIT 1000 ) # calculate aggregations on stream for reporting: SELECT ROW_NUMBER() OVER() AS dashboard_sort, minute, COUNT(DISTINCT ride_id) AS total_rides, SUM(meter_reading) AS total_revenue, SUM(passenger_count) AS total_passengers FROM streaming_data GROUP BY minute, timestamp The text says that the result shows key metrics by the minute for every taxi drop-off. However, by grouping per timestamp and minute, you are doing a data-summary by row and not by minute. Finally, 2 minutes were not enough to collect drop-off data to create the final plot, at least in my case. Cheers, Giacomo
