Anthony,
You can use a complex object with several fields as a value. Use
@QuerySqlField annotation to annotate queried and/or indexed fields and use
these fields in your SQL query.
So in your case it will be smth like this:
class Instrument {
@QuerySqlField(index = true)
private String symbol;
private double price;
}
And the query will be: "select symbol, count(symbol) as cnt from Instrument
group by symbol"
Here is the documentation page for more information on queries API:

Thanks!
