--------------------------------
Labels: starter (was: )
> Add execution modes for programs
> --------------------------------
>
> Key: FLINK-1671
> URL: https://issues.apache.org/jira/browse/FLINK-1671
> Project: Flink
> Issue Type: Bug
> Affects Versions: 0.9
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Fix For: 0.9
>
>
> Currently, there is a single way that programs get executed: Pipelined. With
> the new code for batch shuffles (https://github.com/apache/flink/pull/471),
> we have much more flexibility and I would like to expose that.
> I suggest to add more execution modes that can be chosen on the
> `ExecutionEnvironment`:
> - {{BATCH}} A mode where every shuffle is executed in a batch way, meaning
> preceding operators must be done before successors start. Only for the batch
> programs (d'oh).
> - {{PIPELINED}} This is the mode corresponding to the current execution
> mode. It pipelines where possible and batches, where deadlocks would
> otherwise happen. Initially, I would make this the default (be close to the
> current behavior). Only available for batch programs.
> - {{PIPELINED_WITH_BATCH_FALLBACK}} This would start out with pipelining
> shuffles and fall back to batch shuffles upon failure and recovery, or once
> it sees that not enough slots are available to bring up all operators at once
> (requirement for pipelining).
> - {{STREAMING}} This is the default and only way for streaming programs.
> All communication is pipelined, and the special streaming checkpointing code
> is activated.
