Description

The purpose of this task is to make an ExecNode that can provide the following functionality.

1. Be able to obtain heuristics about our memory consumption and have a memory consumption threshold

1. Be able to write incoming ExecBatch to disk if memory consumption is above the threshold, stores either the ExecBatch or a handle to file in a queue.

1. Provide an api for pulling an ExecBatch from the queue. It should favor pulling all of the batches that are in memory first and then the ones that are handles to files.
