Stephan Ewen commented on FLINK-1198:
-------------------------------------
I have worked in this issue already for the past week and have it running
(including iterations) except for compatibility with the deprecated record API.
I think it easier if I just finish that part, since the tricky cases are all
done.
> Store broadcast variables once per TaskManager

> Components: Local Runtime
> Affects Versions: 0.7.0-incubating
> Reporter: Stephan Ewen
> Assignee: Alexander Alexandrov
> Fix For: 0.8-incubating

> Currently, a copy of the broadcast variable is sent to each parallel task,
> rather than once to the TaskManager where the tasks share them.
> Sharing the braodcast variables would increase memory efficiency
> significantly.
