Stephan Ewen closed FLINK-2084. ------------------------------- > Create a dedicated streaming mode > --------------------------------- > > Key: FLINK-2084 > URL: https://issues.apache.org/jira/browse/FLINK-2084 > Project: Flink > Issue Type: Improvement > Components: Distributed Runtime > Affects Versions: 0.9 > Reporter: Stephan Ewen > Assignee: Stephan Ewen > Fix For: 0.9 > > > As per discussion on the mailing list > http://mail-archives.apache.org/mod_mbox/flink-dev/201505.mbox/browser > - We add a dedicated streaming mode for now. The streaming mode supersedes > the batch mode, so it can run both type of programs. > - The streaming mode sets the memory manager to "lazy allocation". > -> So long as it runs pure streaming jobs, the full heap will be > available to window buffers and UDFs. > -> Batch programs can still run, so mixed workloads are not prevented. > Batch programs are a bit less robust there, because the memory manager does > not pre-allocate memory. UDFs can eat into Flink's memory portion. > - The streaming mode starts the necessary configured components/services for > state backups > Over the next versions, we want to bring these things together: > - use the managed memory for window buffers > - on-demand starting of the state backend > Then, we deprecate the streaming mode, let both modes start the cluster in > the same way. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
