Hi, I'd like to make the question more specific. Here's my use-case: I have to store a huge number of latitute (lat) and longitude (long) values. And i have to find the nearest lats and longs to a given lat-long. Is there an efficient way to do this in Impala? Thanks.

Greetings. Is there an efficient way to do range queries in Impala? For example, I have a column called latitude of type Double. I'd like to find all rows whose latitude is between the range x-5 and x+5, where x is a double. I can scan all rows, but that's O(n). Is there a more efficient way, one that can give results in real-time with a billion rows? Thanks.
