Also keep in mind (for subsequent work) that some nodes (ie “Limit” in particular) will need to be able to apply backpressure on their parents to get them to immediately quit producing outputs. For example, if you have a “limit 1000” query, as soon as you have 1000 rows of output you shut down the ancestors. -- This is an automated message from the Apache Git Service.
