Subject [jira] [Commented] (FLINK-1198) Store broadcast variables once per TaskManager
Date Sat, 01 Nov 2014 19:35:33 GMT

    [ https://issues.apache.org/jira/browse/FLINK-1198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14193391#comment-14193391

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.

>          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.
