Graphql-engine: Add aggregation queries for computed fields

[tafelito]

Are you planning to add aggregation queries to computed fields?

[rakeshkky]

@tafelito Yes, indeed. We will add support for aggregation queries on computed fields returning a set of table rows. :slightly_smiling_face:

[pankgeorg]

Is there a timeline for that?

[janhaa]

Any update on this?

[hthillman]

Seconded, it's possible to work around this using a view but allowing aggregations on computed fields would make it much easier
