kennknowles opened a new issue, #18423: URL: https://github.com/apache/beam/issues/18423
Currently there is no functionality allowing to read only keys from the Google Datastore through the Datastore IO. In some cases users don't need to read the whole entity, e.g. to filter by certain values in ancestry. This seems to be an important feature as the entity reads are expensive and thus the native Datastore client/API allow to run Key Only queries. Imported from Jira [BEAM-2819](https://issues.apache.org/jira/browse/BEAM-2819). Original Jira may contain additional context.
