Yuzhang QIU commented on KYLIN-2575: ------------------------------------ Hi Shaofeng, Kylin Enterprise Edition has this feature, and it makes the dataware house transparent to analysts. We don't need extra maintanence on view when change the computed column expression. > Experimental feature: Computed Column > ------------------------------------- > > Key: KYLIN-2575 > URL: https://issues.apache.org/jira/browse/KYLIN-2575 > Project: Kylin > Issue Type: New Feature > Reporter: hongbin ma > Assignee: hongbin ma > Priority: Major > > Computed column is a virtual column that is calculated from an expression of > existing columns. For example, TAX is computed from PRICE * TAX_RATE; TX_YEAR > is from EXTRACT(year from TX_DATE). > Currently user have to create a view to enrich these computed columns, then > feed the view to cube. This has two inconvenience: > Create a view is not easy. > The query has to be rewritten to use view instead of the original table. > Let Kylin directly support computed column will be a big step forward. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
