Review comment:
Can we use `str.format()` instead of `%`? Some
[example](https://realpython.com/python-f-strings/#option-1-formatting).
`str.format()` is ported back to Python 2.7, so it should be available. But
since this is outside of `interactive` package, we can just leave it as it is.

> This issue tracks the work items to introduce streaming support to the
> Interactive Beam experience. This will allow users to:
> * Write and run a streaming job in IPython
> * Automatically cache records from unbounded sources
> * Add a replay experience that replays all cached records to simulate the
> original pipeline execution
> * Add controls to play/pause/stop/step individual elements from the cached
> records
> * Add ability to inspect/visualize unbounded PCollections
