> Currently InteractiveRunner wraps every record of the cached PCollection into
> WindowedValue. There is 2 problems about this:
> 1) The windowing information is unnecessary for the batch-mode runs
> (everything is in the same global window).
> 2) Since the cache is stored as text, we pickle the WindowedValue, which adds
> ~500 bytes of data to every record (e.g. a cache of just 1000000 integers
> would take ~500MB instead of ~4MB).
> These issues significantly slow down the interactive runs for data with lots
> of small rows.
