Got exception if I have more than 1 aggregation in SQL for MongoDB:

Original SQL

SELECT COUNT(MongoNestedDocDS.addresst.age) AS c_0, SUM(MongoNestedDocDS.addres
st.age) AS c_1 FROM MongoNestedDocDS.addresst LIMIT 1000

Got exception:

Caused by: org.teiid.jdbc.TeiidSQLException: TEIID30504 -1880007235: TEIID18024 multiple aggregate symbols are not sup

Can we consider to use in memory engine instead if more than 1 aggregation?
