   ## Proposed changes
   
   Support Alluxio Local Cache + Soft Affinity to speed up the query performance on the cloud.
   Support Spark 3.1 only.
   
   ## Github Branch 
   
   As most of the development works are on Kylin 4, we need to switch it as main branch. Apache Kylin community changes the branch settings on Github since 2021-08-04 :
   
   1. The default branch _main_ is for **Kylin 4.x** (Parquet storage);
   2. The original branch _master_ for **Kylin 3.x** (HBase storage) has been renamed to **kylin3** ;
   
   Please check [Intro to Kylin 4 architecture](https://kylin.apache.org/blog/2021/07/02/Apache-Kylin4-A-new-storage-and-compute-architecture/) and [INFRA-22166](https://issues.apache.org/jira/browse/INFRA-22166) if you are interested.
