This tutorial will guide you to create a hybrid model. Regarding the concept of hybrid, please refer to [this blog](http://kylin.apache.org/blog/2015/09/25/hybrid-model/).

### I. Create a hybrid model
One Hybrid model can refer to multiple cubes.

1. Click `Model` in top bar, and then click `Models` tab. Click `+New` button, in the drop-down list select `New Hybrid`.

2. Click `Submit` to save the Hybrid model. 

Now you only can view hybrid details by click `Edit` button.

### III. Drop a hybrid model
1. Place the mouse over the Hybrid name, then click `Action` button, in the drop-down list select `Drop`. Then the window will pop up. 

2. Click `Yes` to drop the Hybrid model. 

### IV. Run Query
After the hybrid model is created, you can run a query. As the hybrid has higher priority than the cube, queries will already hit the hybrid model, and then be delegated to cubes. 

Click `Insight` in top bar, input a SQL statement to execute.

*Please note, Hybrid model is not suitable for "bitmap" count distinct measures's merge across cubes, please have the partition date as a group by field in the SQL query. *
