Alexander Alexandrov commented on FLINK-1198:
---------------------------------------------
Can start working on this on Nov 10th. Can you give me some points which
components to extend? We have to make sure that the task managers release the
allocated objects once the UDFs / jobs that need them are no longer alive.
> 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.
