• Cloud Dataflow takes a query and runs information from the database through it to produce tables of data organized according to the requirements of the original query.
• Cloud Dataflow relies on a large database to store and analyze data processing pipelines, performing transforms resulting in predictive analytics that can be leveraged to optimize business decisions.
• Cloud Dataflow relies on training data to enable machine learning that can then read multiple streams of data and perform transforms that produce resulting output data.
• Cloud Dataflow reads data in and can apply filtering, grouping, comparing, joining, or aggregation

The correct answer is:

• Cloud Dataflow reads data in and can apply filtering, grouping, comparing, joining, or aggregation.
