             Summary: Use Spark 3 as build and query engine for Kylin 4
                 Key: KYLIN-4925
                 URL: https://issues.apache.org/jira/browse/KYLIN-4925
             Project: Kylin
          Issue Type: New Feature
          Components: Job Engine, Query Engine
            Reporter: Congling Xia
            Assignee: Congling Xia
             Fix For: v4.0.0-GA


Spark 3 provides much more developed AQE framework, DPP and the increased 
support for GPUs and Kubernetes. The perspectives of performance increase are 
very promising. 

Currently, we try to run Kylin 4.0 with Spark 3.0 as build & query engine. We'd 
like to share the code changes here.
