MIN example: Window function 
SELECT "trip_distance_mi", MIN("total_amount")
  OVER (PARTITION BY "trip_distance_mi") "min_total_amount"
FROM "Samples"."samples.dremio.com"."NYC-taxi-trips"
LIMIT 1;
-- trip_distance_mi, min_total_amount
-- 0.09, -52.5
MIN example: Window function with cumulative window frame 
SELECT city, state, pop, MIN(pop)
  OVER (PARTITION BY state ORDER BY city RANGE BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING) 
FROM Samples."samples.dremio.com"."zips.json";
-- city, state, pop, EXPR$3
-- 98791, AK, 5345, 0
-- AKHIOK, AK, 13309, 0
-- AKIACHAK, AK, 481, 0
-- ...
MIN example: Window function with sliding window frame 
SELECT city, state, pop, MIN(pop)
  OVER (PARTITION BY state ORDER BY city ROWS BETWEEN 1 PRECEDING AND 2 FOLLOWING)
FROM Samples."samples.dremio.com"."zips.json";
-- city, state, pop, EXPR$3
-- 98791, AK, 5345, 481
-- AKHIOK, AK, 13309, 285
-- AKIACHAK, AK, 481, 285
-- ...
