Shaofeng SHI commented on KYLIN-906:
------------------------------------
Vipul, yes, in web page we will ask user to enter the Day nubmers to keep; in
the backend cube metadata we will set the retention as a long value in
millisecond to keep maximum flexibility and also be consistent with other parts;

> URL: https://issues.apache.org/jira/browse/KYLIN-906
> Project: Kylin
> Issue Type: New Feature
> Components: General
> Reporter: vipul jhawar
>
> As a developer I would like to specify a data retention range for my cube as
> when the cubes are being generated with a lot of dimensions with high
> cardinality, we may not want to store the data forever.
> Having a option to define if the retention range for a cube is moving range
> of 7, 30, 90 ... days is helpful as then I can go for larger cubes for
> shorter times when the resources available are limited and the data purge is
> also handled in the system.
> We currently have daily build size of 60G without including the case for
> unique users (which is around 300 G), so we may want to limit the unique user
> cube to 7 days and other cube to 100 days.
