>
> 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.).
