I was a little confusing by the statement "Samza takes a different approach to buffering. We buffer to disk at every hop between a StreamTask. <http://samza.incubator.apache.org/learn/documentation/0.7.0/comparisons/storm.html> ".
What does "buffer to disk" mean here? I actually do not get how we deal with the situation when the processing is slower than receiving messages. Thank you. Cheers, Fang, Yan [email protected] +1 (206) 849-4108
