Practical On-line Approximation Algorithms in Storm with Ted Dunning

Dear friends,

This time we will have Ted Dunning - Chief Application Architect at MapR, speaking about "Practical On-line Approximation Algorithms in Storm."

There are lots of things that are easy to compute if you have all the data in hand, but hard to compute exactly in an on-line fashion with limited memory. Examples include count(distinct), percentiles and heavy hitters (top-40). On the other hand, Storm really prefers that we compute in an on-line fashion with limited memory. Happily, there are approximate algorithms for these quantities that are relatively easy to use, have tunable accuracy, and are fast. Unfortunately, these algorithms are not widely known. I will describe several of these algorithms and how they can be used in Storm.

We will also have welcome note from Geir Magnusson, AppNexus CTO.
