Summary: Kylin Auto Data Retention
Key: KYLIN-1406
URL: https://issues.apache.org/jira/browse/KYLIN-1406
Project: Kylin
Issue Type: Task
Reporter: qianqiaoneng
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.
