EDjur commented on BEAM-7577:
-----------------------------
I'd be happy to give a go att adding this functionality for the query filters
but I might need someone to point me in the right direction first.
> Allow the use of ValueProviders in
> datastore.v1new.datastoreio.ReadFromDatastore query
> --------------------------------------------------------------------------------------

> Key: BEAM-7577
> URL: https://issues.apache.org/jira/browse/BEAM-7577
> Project: Beam
> Issue Type: New Feature
> Components: io-python-gcp
> Affects Versions: 2.13.0
> Reporter: EDjur
> Priority: Minor
>
> 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 at runtime.
>
> 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).
