Aggregation queries not (yet) supported by the emulator

[stickfigure]

Trying to run aggregation queries in the emulator produces this error:

com.google.datastore.v1.client.DatastoreException: Method google.datastore.v1.Datastore/RunAggregationQuery is unimplemented, code=UNIMPLEMENTED

This is causing problems for Objectify users because count() is now implemented as an aggregation. Great for production, but tests no longer work :-(

We'd really like to have this implemented in the emulator 🙏🏻

Any updates on this? it would be nice to be able to test the new aggregations.

Any updates on this? We would need this feature as well, for our integration tests.

Also need this ☹️

We would really like this as well. Trying to migrate off Count calls, which are deprecated, but we won't do it if it breaks our tests. Any updates here?
