> We use Zookeeper znodes to transfer aggregated values from workers to master and back. Zookeeper is supposed to be used for coordination, and it also has a memory limit which prevents users from having aggregators with large value objects. These are the reasons why we should implement aggregators gathering and distribution in a different way.
