Architecture of Read-Write Separation



  1. Kylin 4.0 uses the Yarn resources on build cluster to build cube data and then write the cube data back to the HDFS on query cluster directly.
  2. Build jobs read the Hive data sources which are on build cluster.
  3. When executing pushdown query, Kylin 4.0 reads the Hive data from build cluster.
