Hi, I have to calculate some complicated metrics like click through rate , click value rate and conversions on real time data using flink. But I am not sure what functionality of flink should I use to program this because it involves collection of some records in memory for certain time may be 1 minute and then using formula for calculating metrics on those records.
Am I correct with my approach or is there any preferred approach for such tasks in flink? Can I use windows for doing this? Any tutorial or example would be really great. Rahul Raj
