Summary: Allow for aggregate queries in Python MongoDBIO Read
Key: BEAM-8887
URL: https://issues.apache.org/jira/browse/BEAM-8887
Project: Beam
Issue Type: New Feature
Components: io-py-mongodb
Reporter: Corvin Deboeser
Assignee: Yichi Zhang

complicated queries as input to a beam pipeline. Example use cases are sampling
data ($sample), joining foreign data ($lookup),
