If the source table structure changed in Hive, How should I cope with the model and cube which have been created for a time?

Hi! Dear kyliners:
&nbsp; &nbsp;
&nbsp; &nbsp; &nbsp; &nbsp;There is a question confused me for a long time. In some situations, we would change the table structure in&nbsp; Hive. For those tables which were loaded


from Hive, we have used it to create the model and build cube in kylin. But if the Hive source table structures have been changed, it would reduce the cube&nbsp;


even the model to be ineffective.&nbsp;


&nbsp; &nbsp; &nbsp; &nbsp;What I want to&nbsp; know is there any better and&nbsp;more sophisticated&nbsp;solutions other than delete the cube or delete the model. Because it costs me too much&nbsp;


time on creating model and cube.&nbsp;


ps:My kylin env is 2.6.3 and Hive env is 3.1.0.
