System Cube and Dashboard Not well tested, planning Read write Seperatation New implementation provided Pushdown Engine New pushdown engine will only support SparkSQL. Shrunken Dictionary This feature maybe useless UHC dictionary This feature maybe useless Deploy on AWS EMR Planning Containerization Planning Hadoop3 support Going to support Hadoop3 + Hive2 in 2020-Q4. Not sure when to suppoort Hive 3. Hive3 support Spark3 support
