With over 600 talk submissions, conference organizers curated a program comprised of 120 talks and panels and over 130 speakers and panelists. Unlike research conferences, code.talks does not target researchers, but rather developers instead. Their main objective is to provide developers with inspiring experiences. Talks cover a wide range of topics, including user stories, use-cases, developer experiences, creative solutions, big data architectures, web technologies, programming tutorials, system presentations, and research, among others.
Philipp Grulich and Jonas Traub are researchers in the Database Systems and Information Management Group at TU Berlin (TUB) and the Intelligent Analytics for Massive Data Research Department at the German Research Center for Artificial Intelligence (DFKI) contributed to the “Big Data” track.
In the panel discussion on “GDPR – Who cares?” Heike Wolters (Xing) discussed experiences, challenges, and opportunities related to the EU GDPR (General Data Protection Regulation) with Verena Grentzenberg (DLA PIPER), Wolfram Wingerath (Universität Hamburg), and Jonas Traub.
Additionally, in their talk entitled “Scotty: Efficient Window Aggregation for your Stream Processing System”, Philippand Jonasjointlyfrom TUB und DFKI presented their work on the Scotty Window Processor, which enables high-throughput window aggregations in stream processing systems. The talks introduced the concept of stream slicing, in order to share partial aggregates among overlapping windows. Scotty works as a drop-in replacement for window operators in stream processing engines, like Apache Flink and Storm. With its Apache Beam connector, Scotty can also be integrated into Google Cloud Dataflow. Scotty is the result of a cooperative work, which originated at KTH Stockholm and RISE SICS, with the Cutty Project [1] and evolved to the generally applicable solution, which received the best paper award at EDBT 2019 [2,3].
