Session Title: Stream Processing: What's Tough about Streams

Processing an unbounded sequence of data in real-time presents many difficulties not present in traditional batch-oriented processing methods.  Problems that are trivial in the batch world can be quite a bit tougher when presented as a streaming problem.  For example, streaming programs are never meant to terminate.  Calculations and stateful processing must be handled carefully to ensure consistency and correctness. 
In this talk I'll present you with one such problem - computing ad clickthrough rates - and use it to illustrate pitfalls that can arise in streaming data situations.  I'll discuss a few streaming systems, with particular emphasis on Apache Storm, Apache Spark Streaming, and Apache Kafka.
