sunny209868 commented on issue #3539: PQL Support for generalized expressions in selection and aggregation
URL: https://github.com/apache/incubator-pinot/issues/3539#issuecomment-492204053
> Doing expressions on the client side (in the select statement) can be done on the client but it is essentially an involved operation:
>
> Consider a contrived query like this: Select mul(foo, 2), div(foo, bar) from Table where mul(baz, 4) = 10.
>
> If this query is generated in an adhoc manner, the client would have to have support for parsing this query and figuring out that the foo, bar need to multiplied like so and that baz has to be ignored. That's a lot to ask from a client and it is something that would be easier to implement in the database itself.
>
> Can you help me understand how much work would it be to implement such features ? I am happy implementing if they won't require a lot of architectural changes :-)
