The underlying motivation for FLIP-6 was the fact that Flink is being +adopted by a wider range of developer communitiesâboth developers coming from the big data and +analytics space as well as developers coming from the event-driven applications space.</p> + +<p>Modern, stateful stream processing has served as a convergence for these two developer communities. +Despite a significant overlap of the core concepts in the applications being built, each group of +developers has its own set of common tools, deployment models, and expected behaviors when working +with a stream processing framework like Flink.</p> + +<p>FLIP-6 will ensure that Flink fits naturally in both of these contexts, behaving as though itâs +native to each ecosystem and operating seamlessly within a broader technology stack. A few of the +specific changes in FLIP-6 that will have such an impact:</p> + +<ul> + <li>Leveraging cluster management frameworks to support full resource elasticity</li> + <li>First-class support for containerized environments such as Kubernetes and Docker</li> + <li>REST-based client-cluster communication to ease operations and 3rd party integrations</li> +</ul> + +<p>FLIP-6, along with already-introduced features like +<a href="https://data-artisans.com/blog/apache-flink-at-mediamath-rescaling-stateful-applications";>rescalable state</a>, +lays the groundwork for dynamic scaling in Flink, meaning that Flink programs will be able to scale up or down +automatically based on required resourcesâa huge step forward in terms of ease of operability and +the efficiency of Flink applications.</p> + +<h2 id="lower-latency-via-improvements-to-the-apache-flink-network-stack">Lower Latency via Improvements to the Apache Flink Network Stack</h2> + +<p>Speed will always be a key consideration for users who build stream processing applications, and +Flink 1.5 will include a rework of the network stack that will even further improve Flinkâs latency. +At the heart of this work is a transition from configurable, fixed-interval network I/O to event- +driven network I/O and application-level flow control, ensuring that Flink will use all available +network capacity, as well as credit-based flow control which offers more fine-grained backpressuring +for improved checkpoint alignments.</p> + +<p>In our testing (<a href="https://www.slideshare.net/FlinkForward/flink-forward-berlin-2017-nico-kruber-building-a-network-stack-for-optimal-throughput-lowlatency-tradeoffs";>see slide 26 here</a>), +weâve seen a substantial improvement in latency using event-driven network I/O, and the community +is also doing work to make sure weâre able to provide this increase in speed without a measurable +throughput tradeoff.</p> + +<h2 id="faster-recovery-from-failures">Faster Recovery from Failures</h2> + +<p>Flink 1.3.0 introduced incremental checkpoints, making it possible to take a checkpoint of state +updates since the last successfully-completed checkpoint only rather than the previous behavior of +only taking checkpoints of the entire state of the application. This has led to significant +performance improvements for users with large state.</p> + +<p>Flink 1.5 will introduce task-local recovery, which means that Flink will store a second copy of the +most recent checkpoint on the local disk (or even in main memory) of a task manager. The primary +copy still goes to durable storage so that itâs resilient to machine failures.</p> + +<p>In case of failover, the scheduler will try to reschedule tasks to their previous task manager (in +other words, to the same machine again) if this is possible. The task can then recover from the +locally-kept state. This makes it possible to avoid reading all state from the distributed file +system (which is remote over the network). Especially in applications with very large state, not +having to read many gigabytes over the network and instead from local disk will result in +significant performance gains in recovery.</p> + +<h2 id="the-proposed-timeline-for-flink-14-and-flink-15">The Proposed Timeline for Flink 1.4 and Flink 1.5</h2> + +<p>The good news is that all 3 of the features described above are well underway, and in fact, much of +the work is already covered by open pull requests.</p> + +<p>But given these featuresâ importance and the complexity of the work involved, the community expected +that the QA and testing required would be extensive and would delay the release of the otherwise- +ready features also on the list for the next release.</p> + +<p>And so the community decided to withhold the 3 features above (deployment model rework, improvements +to the network stack, and faster recovery) to be included a separate Flink 1.5 release that will +come shortly after the Flink 1.4 release. Flink 1.5 is estimated to come just a couple of months +after 1.4 rather than the typical 4-month cycle in between major releases.</p> + +<p>The soon-to-be-released Flink 1.4 represents the current state of Flink without merging those 3 +features. And Flink 1.4 is a substantial release in its own right, including, but not limited to, +the following:</p> + +<ul> + <li><strong>A significantly improved dependency structure</strong>, removing many of Flinkâs dependencies and subtle runtime conflicts. This increases overall stability and removes friction when embedding Flink or calling Flink âlibrary styleâ.</li> + <li><strong>Reversed class loading for dynamically-loaded user code</strong>, allowing for different dependencies than those included in the core framework.</li> + <li><strong>An Apache Kafka 0.11 exactly-once producer</strong>, making it possible to build end-to-end exactly once applications with Flink and Kafka.</li> + <li><strong>Streaming SQL JOIN based on processing time and event time</strong>, which gives users the full advantage of Flinkâs time handling while using a SQL JOIN.</li> + <li><strong>Table API / Streaming SQL Source and Sink Additions</strong>, including a Kafka 0.11 source and JDBC sink.</li> + <li><strong>Hadoop-free Flink</strong>, meaning that users who donât rely on any Hadoop components (such as YARN or HDFS) in their Flink applications can use Flink without Hadoop for the first time.</li> + <li><strong>Improvements to queryable state</strong>, including a more container-friendly architecture, a more user-friendly API that hides configuration parameters, and the groundwork to be able to expose window state (the state of an in-flight window) in the future.</li> + <li><strong>Connector improvements and fixes</strong> for a range of connectors including Kafka, Apache Cassandra, Amazon Kinesis, and more.</li> + <li><strong>Improved RPC performance</strong> for faster recovery from failure</li> +</ul> + +<p>The community decided it was best to get these features into a stable version of Flink as soon as +possible, and the separation of what could have been a single (and very substantial) Flink 1.4 +release into 1.4 and 1.5 serves that purpose.</p> + +<p>Weâre excited by what each of these represents for Apache Flink, and weâd like to extend our thanks +to the Flink community for all of their hard work.</p> + +<p>If youâd like to follow along with release discussions, <a href="http://flink.apache.org/community.html#mailing-lists";>please subscribe to the dev@ mailing +list</a>.</p> + + + </article> + </div> + + <div class="row"> + <div id="disqus_thread"></div> + <script type="text/javascript"> + /* * * CONFIGURATION VARIABLES: EDIT BEFORE PASTING INTO YOUR WEBPAGE * * */ + var disqus_shortname = 'stratosphere-eu'; // required: replace example with your forum shortname + + /* * * DON'T EDIT BELOW THIS LINE * * */ + (function() { + var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true; + dsq.src = '//' + disqus_shortname + '.disqus.com/embed.js'; + (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq); + })(); + </script> + </div> + </div> +</div> + </div> + </div> + + <hr /> + + <div class="row"> + <div class="footer text-center col-sm-12"> + <p>Copyright © 2014-2017 <a href="http://apache.org";>The Apache Software Foundation</a>.
