--------------------------
Resolution: Fixed
Fix Version/s: 0.3.0-incubating
> Spark batch interval should be a configuration instead of an interpretation
> of the Pipeline's windows

> Project: Beam
> Issue Type: Bug
> Components: runner-spark
> Reporter: Amit Sela
> Assignee: Amit Sela
> Fix For: 0.3.0-incubating
>
>
> Currently, the SparkRunner extracts the batch interval from the duration of
> the first window.
> This is wrong in several ways:
> # GlobalWindow pipelines
> # It's an engine specific property and should not be expressed as a part of
> the logic but rather as a configuration for execution of the pipeline.
> # Effectively forces the definition of Fixed/SlidingWindows even when they
> are not needed (stateless processing), which also makes the pipeline code not
> portable.
