                 Key: DELTASPIKE-709
                 URL: https://issues.apache.org/jira/browse/DELTASPIKE-709
             Project: DeltaSpike
          Issue Type: Improvement

It will be nice if query expressions has the following features:

- Support aggregate functions. Examples:

'''
Long countByName(String name);
Long countDistinctByName(String name);
Double sumPriceByCategory(Category category);
BigDecimal avgPriceByCategory(Category category);
'''

- Support GROUP BY and HAVING clauses.

'''
List<Product> findByNameGroupByName(String name);
List<Product> findByNameGroupByNameHavingNameLike(String name);
'''
