Title:          "Flink: Next-Generation Data Analytics"

Abstract:

Apache Flink (http://flink.incubator.apache.org) is a software stack for
complex big data analytics, which is a result of the Stratosphere research
project coordinated at TU Berlin. Flink covers a variety of use cases,
such as data warehousing, information extraction and integration, data
cleansing, graph analysis, and statistical analysis applications. Flink
brings together a unique set of features from database systems and
MapReduce-like technology that enables expressive, easy, and efficient
programming for the development of large-scale analytical applications. It
features include in situ data processing, multiple language APIs (e.g.,
for Java and Scala), treatment of user-defined functions (UDFs) as
first-class citizens, automatic program parallelization and optimization,
support for iterative programs, and a scalable and efficient execution
engine. In this talk, I will present an overview of the Stratosphere
vision, the Flink platform as well as current and future research
activities.
