> I don't think independent ExecNodes would work, since some operations (e.g. hash aggregation or any vector function) need access to the entire input before starting to compute their output. Note: Hash aggregation does not need access to its entire input to start computing, and in the first iteration of this project vector functions will be entirely disallowed. -- This is an automated message from the Apache Git Service.
