Review comment:
Sorry for the delay; you're right that setting tuple as the type won't work
here since it needs to be initialized from a string.

> The current implementation of ReadFromDatastore does not support specifying
> the query parameter at runtime. This could potentially be fixed through the
> usage of a ValueProvider to specify and build the Datastore query.
> Allowing specifying the query at runtime makes it easier to use dynamic
> queries in Dataflow templates. Currently, there is no way to have a Dataflow
> template that includes a dynamic query (such as filtering by a timestamp or
> similar).
