<h1>Apache YuniKorn (incubating) Release Notes v0.8.0</h1>

<!--
<div class="col-md-6">
<p>This is the first release of Apache YuniKorn (incubating).</p>
<h2>Overview</h2>
<p>The Apache YuniKorn (Incubating) community has fixed 60 JIRAs in this release: <a href="https://issues.apache.org/jira/issues/?filter=12348926">YuniKorn jiras fixed in 0.8.0</a></p>
<h2>Highlights</h2>
<h3>Queues and placement rules</h3>
<p>With this new dynamic queue management feature, users can set up placement rules to delegate queue management.</p>
<p>This enables use cases like mapping a K8 namespace to a YuniKorn queue without the need to pre-create all queues.</p>
<p>Queues are created based on placement rules when required for running an application. Dynamic queues are deleted when no longer required.</p>
<h3>Pluggable Application Management</h3>
<p>A pluggable app management framework is being added to this release, with this feature, YuniKorn can be easily integrated with 3rd party K8s operators, such as Spark-k8s-operator, Flink-k8s-operator, etc.</p>
<h3>Resource Reservation</h3>
<p>Reservation is the methodology used to avoid large/picky resource requests being starved in the batch scheduling scenario.</p>
<p>One node is reserved for a specific request from an application, effectively removing it from the available node list for other applications.</p>
<h3>Pluggable Node Sorting Policies</h3>
<p>There are 2 builtin node sorting policies (FAIR and BinPacking) available in YuniKorn with regards to allocation distribution.</p>
<p>The node sorting policies are pluggable, users can implement their own policies and plug that into the scheduler.</p>
<h3>Improved Scheduling Performance</h3>
<p>When running Big Data batch workloads, e.g Spark, on K8s, scheduler throughput becomes one of the main concerns.</p>
<p>In YuniKorn, there are lots of optimizations to improve the performance, such as a fully async event-driven system and low-latency sorting policies.</p>
<p>Based on our test using Kubemark, YuniKorn is 2x+ faster than the default K8s scheduler.</p>

<h2>Community</h2>
<p>Since the birth of the YuniKorn project, the feedback has been well-received. We are thankful to have such a diverse community where we have members from Microsoft, LinkedIn, Alibaba, Apple, Tencent, Nvidia, and Cloudera, to help and guide the project’s growth.</p>
<p>Many thanks to everyone who contributed to the release, and everyone in the Apache YuniKorn (Incubating) community!</p>
<p>The release is a result of direct and indirect efforts from many contributors, listed below are those who contributed directly by submitting patches: Adam Antal, Akhil Puthenveettil Balan, Bhuvan Mysore, Jetly Jaimin, Kinga Marton, Sunil Govindan, Tao Yang, Tarun Parimi, Wangda Tan, Wanqiang Ji, Weiwei Yang, Wilfred Spiegelenburg, Vinod Kumar Vavilapalli.</p>
