-----------------------------------
Summary: Only keep base cuboid files on HDFS for future merge
Key: KYLIN-3435
URL: https://issues.apache.org/jira/browse/KYLIN-3435
Project: Kylin
Issue Type: Improvement
Components: Job Engine
Reporter: Shaofeng SHI
Today Kylin keeps all cuboids data in HDFS for future merge. When doing the
merge, Kylin need re-encode the dimension values with the new dictionaries, for
all cuboids.
If we only keep the base cuboid, lots of disk space can be saved. On merge,
after merge the base cuboid, calculate others from the new base cuboid.
