Athena Table for ALB Logs

alb_logs.sql

-- This creates an athena table that can parse ALB logs.
-- Advantage of this over others are this works when the log ends with a trailing space
-- plus it also breaks the http request into route and params for easier grouping

doesn't work... i'm getting zero records... can someone advise on the possible problem? running the aws tutorial worked

Is there a way to import time as timestamp instead of string, this make queries slow as each record requires parsing.

I was facing the same issue. It's because the location does not hold any logs. Check the location
