liyang commented on KYLIN-3739: ------------------------------- Sounds fine to me if we can keep it backward compatible. I guess the logic will be, first check if the name is an alias, and if not then check if it's a full table name. Should be a small change by line of code I assume. > Use table alias rather than table identity for snapshots in CubeSegment, > CubeInstance, CubeDesc > ----------------------------------------------------------------------------------------------- > > Key: KYLIN-3739 > URL: https://issues.apache.org/jira/browse/KYLIN-3739 > Project: Kylin > Issue Type: Improvement > Components: Metadata > Reporter: Zhong Yanghong > Priority: Major > > In 2.0.0, Kylin introduced table alias in DataModelDesc. Most of the elements > in CubeDesc, CubeInstance & CubeSegment use the table alias rather than the > table identity. However, for the lookup table snapshots, it still uses table > identity. > It's better for us to use only table alias instead of table identity in > CubeDesc, CubeInstance & CubeSegment. If so, it can provide several > advantages: > # For CubeDesc, CubeInstance & CubeSegment, what exposed to them is only the > snowflake model and they don't need to care which real table is used. > # If users want to change the table name in the snowflake model, we can still > keep the table alias unchanged and what we need to change is only the > DataModelDesc. And we don't need to do any change for CubeDesc, CubeInstance > & CubeSegment. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
