Subject [GitHub] flink pull request: [FLINK-1730]Persist operator on Data Sets
Date Wed, 09 Sep 2015 10:34:36 GMT
Github user sachingoel0101 commented on the pull request:

    I apologize. Like I said before, the way I've implemented this, it seemed pretty trivial.
Foremost, I needed this for something else and decided to take a shot at it. Missed the finer
details, going by your comments.
    You're right though. Back-tracking the execution graph will most certainly be a better
    @StephanEwen , am I correct in assuming this functionality will be added after (or along
with) Job Session management?
    [As for the memory issue though, if data is to be persisted across jobs, we'll always
have to keep the memory segments allocated even after the job finishes. This is why I defined
a separate owner, which can be later *garbage collected* through a cache freeing mechanism.]
    As far as merging it is considered, I wasn't sure myself from the beginning. I had actually
written an email with a link to my branch for opinions, but ended up opening a PR instead
of sending that. So no worries. I'm closing this.
