Overhauling Apache Kylin for the cloud

Recently, the Apache Kylin community released a major update with the general availability of Kylin 4. Kylin 4 continues the mission to provide a unified, high-performance, cloud-friendly, open source OLAP (online analytical processing) platform. Kylin 4 upgrades the Kylin architecture to make it easy to deploy and scale in the cloud. The new release features three major platform updates and myriad other improvements.

First, Kylin 4 replaces its previous HBase storage engine with Apache Parquet, making it possible to decouple compute and storage for unlimited independent scalability. Second, Kylin 4 unifies the compute engine and removes any previous dependencies on the Hadoop ecosystem. This makes resource allocation much more flexible, resulting in a significant reduction in total cloud resource usage and associated costs. Third, by introducing a brand new, fully distributed query engine, Kylin 4 makes cubing duration and query latency much more performant compared to previous releases.
