> As Kylin's strategy is to use space to trade of query time, thus Kylin cubes consume lots of HBase space. And there are always the case that customer doesn't need to query old data, like 2 years old. So enable Kylin to do auto data retention is a valuable feature.  With this feature, user can define its data retention rule when create the project. Then Kylin server will automatically purge relative segments at certain intervals.
