Divide, Distribute and Conquer: Stream v. Batch

Cerner 51 Valley Stream Parkway , Malvern, PA 19355 (map)

Data is flowing everywhere around us, from phones, credit cards, sensor-equipped buildings, vending machines, thermostats, trains, buses,planes, posts to social media, digital pictures and video and so on.Simple data collection is not enough anymore. Most of the current systems do data processing via nightly extract, transform, and load (ETL)operations, which is common in enterprise environments, requires decision makers to wait an entire day (or night) for reports to become available.

But businesses don’t want «Big Data» anymore. They want «Fast Data».What distinguishes a «streaming systems» from the batch systems is that the event stream is unbounded or “infinite” from a system perspective.

Decision-makers need to analyze these streaming events as a whole to make business decisions as new information arrives.In this talk, after a short introduction to common approaches and architectures (lambda, kappa), Viktor will demonstrate how to use open-source steam processing tools (Flink, Kafka Streams, Hazelcast Jet) for stream processing.

Every byte of data has a story to tell, something of significance that will inform the next thing to be done. In a data-driven enterprise, how we move our data becomes nearly as important as the data itself. With greater speed and agility, data’s value increases exponentially.

From its very early days, we have open-sourced <a>Apache Kafka</a>™ and have led it to impressive industry-wide adoption across several thousand companies. Now we are focusing on building a streaming platform to help other companies get easy access to enterprise data as real-time streams.
