The community put significant effort into improving and extending Apache Flink since the last release, focusing on improving the experience of writing and executing data stream processing pipelines in production. Flink version 1.0.0 marks the beginning of the 1.X.X series of releases, which will maintain backwards compatibility with 1.0.0.

Overall, we have seen Flink grow in terms of functionality from an engine to one of the most complete open-source stream processing frameworks available. The community grew from a relatively small and geographically focused team, to a truly global, and one of the largest big data communities in the the Apache Software Foundation. <a href="/2015/12/18/flink-2015-a-year-in-review-and-a-lookout-to-2016/">...</a> </p> <a href="/2015/12/18/flink-2015-a-year-in-review-and-a-lookout-to-2016/">Continue reading »</a> </article> <article class="markdown book-post"> <h3> <a href="/2015/12/11/storm-compatibility-in-apache-flink-how-to-run-existing-storm-topologies-on-flink/">Storm Compatibility in Apache Flink: How to run existing Storm topologies on Flink</a> </h3> December 11, 2015 - <p>Apache Storm was one of the first distributed and scalable stream processing systems available in the open source space offering (near) real-time tuple-by-tuple processing semantics. Initially released by the developers at Backtype in 2011 under the Eclipse open-source license, it became popular very quickly. Only shortly afterwards, Twitter acquired Backtype. Since then, Storm has been growing in popularity, is used in production at many big companies, and is the de-facto industry standard for big data stream processing. <a href="/2015/12/11/storm-compatibility-in-apache-flink-how-to-run-existing-storm-topologies-on-flink/">...</a> </p> <a href="/2015/12/11/storm-compatibility-in-apache-flink-how-to-run-existing-storm-topologies-on-flink/">Continue reading »</a> </article> <article class="markdown book-post"> <h3> <a href="/2015/12/04/introducing-stream-windows-in-apache-flink/">Introducing Stream Windows in Apache Flink</a> </h3> December 4, 2015 - <p>The data analysis space is witnessing an evolution from batch to stream processing for many use cases. Although batch can be handled as a special case of stream processing, analyzing never-ending streaming data often requires a shift in the mindset and comes with its own terminology (for example, “windowing” and “at-least-once”/”exactly-once” processing). This shift and the new terminology can be quite confusing for people being new to the space of stream processing. <a href="/2015/12/04/introducing-stream-windows-in-apache-flink/">...</a> </p> <a href="/2015/12/04/introducing-stream-windows-in-apache-flink/">Continue reading »</a> </article> <article class="markdown book-post"> <h3> <a href="/2015/11/27/flink-0.10.1-released/">Flink 0.10.1 released</a> </h3> November 27, 2015 - <p>Today, the Flink community released the first bugfix release of the 0.10 series of Flink.

The community put significant effort into improving and extending Apache Flink since the last release, focusing on data stream processing and operational features. About 80 contributors provided bug fixes, improvements, and new features such that in total more than 400 JIRA issues could be resolved. For Flink 0.10.0, the focus of the community was to graduate the DataStream API from beta and to evolve Apache Flink into a production-ready stream data processor with a competitive feature set. <a href="/2015/11/16/announcing-apache-flink-0.10.0/">...</a> </p> <a href="/2015/11/16/announcing-apache-flink-0.10.0/">Continue reading »</a> </article> <article class="markdown book-post"> <h3> <a href="/2015/09/16/off-heap-memory-in-apache-flink-and-the-curious-jit-compiler/">Off-heap Memory in Apache Flink and the curious JIT compiler</a> </h3> September 16, 2015 - <p>Running data-intensive code in the JVM and making it well-behaved is tricky. Systems that put billions of data objects naively onto the JVM heap face unpredictable OutOfMemoryErrors and Garbage Collection stalls. Of course, you still want to to keep your data in memory as much as possible, for speed and responsiveness of the processing applications. In that context, &ldquo;off-heap&rdquo; has become almost something like a magic word to solve these problems. <a href="/2015/09/16/off-heap-memory-in-apache-flink-and-the-curious-jit-compiler/">...</a> </p> <a href="/2015/09/16/off-heap-memory-in-apache-flink-and-the-curious-jit-compiler/">Continue reading »</a> </article> <article class="markdown book-post"> <h3> <a href="/2015/09/03/announcing-flink-forward-2015/">Announcing Flink Forward 2015</a> </h3> September 3, 2015 - <p>Flink Forward 2015 is the first conference with Flink at its center that aims to bring together the Apache Flink community in a single place.

The conference program has been announced by the organizers and a program committee consisting of Flink PMC members.
