This interpreter provides multiple configuration wih ${prefix}. User can set a multiple connection properties by this prefix. It can be used like `%hive(${prefix})`.
### How to use
Basically, you can use
```sql
%hive
select * from my_table;
```
or
```sql
%hive(etl)
-- 'etl' is a ${prefix}
select * from my_table;
```
You can also run multiple queries up to 10 by default. Changing these settings is not implemented yet.
#### Apply Zeppelin Dynamic Forms
You can leverage [Zepplein Dynamic Form](https://zeppelin.incubator.apache.org/docs/manual/dynamicform.html) inside your queries. You can use both the `text input` and `select form` parametrization features
```sql
%hive
SELECT ${group_by}, count(*) as count
FROM retail_demo.order_lineitems_pxf
GROUP BY ${group_by=product_id,product_id|product_name|customer_id|store_id}
ORDER BY count ${order=DESC,DESC|ASC}
LIMIT ${limit=10};
```
