> The portable Flink runner needs to support Flink savepoints for production 
> use. It should be possible to upgrade a stateful portable Beam pipeline that 
> runs on Flink, which involves taking a savepoint and then starting the new 
> version of the pipeline from that savepoint. The potential issues with 
> pipeline evolution and migration are similar to those when using the Flink 
> DataStream API (schema / name changes etc.).
