This means since v3.0 on, Kylin can support sub-second level OLAP over historical batch data, near real-time streaming as well as real-time streaming. The user can use one OLAP platform to serve different scenarios. This solution has been deployed and verified in early adopters like eBay since 2018.

This means since v3.0 on, Kylin can support sub-second level OLAP over historical batch data, near real-time streaming as well as real-time streaming. The user can use one OLAP platform to serve different scenarios. This solution has been deployed and verified in early adopters like eBay since 2018. For how to enable it, please refer to <a href="/docs30/tutorial/realtime_olap.html">this tutorial</a>.</p> - -<h3 id="kylin-3795---submit-spark-jobs-via-apache-livy">KYLIN-3795 - Submit Spark jobs via Apache Livy</h3> -<p>This feature allows the administrator to configure Kylin to integrate with Apache Livy (incubating) for Spark job submissions.
