getAlias

public String getAlias()

 Optional. Optional name of the property to store the result of the
 aggregation.

 If not provided, Datastore will pick a default name following the format
 `property_<incremental_id++>`. For example:

 ```
 AGGREGATE
   COUNT_UP_TO(1) AS count_up_to_1,
   COUNT_UP_TO(2),
   COUNT_UP_TO(3) AS count_up_to_3,
   COUNT(*)
 OVER (
   ...
 );
 ```

 becomes:

 ```
 AGGREGATE
   COUNT_UP_TO(1) AS count_up_to_1,
   COUNT_UP_TO(2) AS property_1,
   COUNT_UP_TO(3) AS count_up_to_3,
   COUNT(*) AS property_2
 OVER (
