---------------------------
Summary: 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: Elias
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).
