I’m trying to bootstrap my operator broadcast state and keyed state using Flink’s State API, and creating a savepoint to initialize my job from.

As far as I can tell, I can create a transformation using a bootstrap function that is either bootstrapping the broadcast state or the keyed state.

The issue is that my operator is a KeyedBroadcastProcessFunction, which handles both regular events and broadcast events, and has a single UID.

When trying to create a savepoint using both transformations on the same UID, it throws an error saying I can’t use the same UID twice.

I tried finding in the documentation and code bootstrap function that supports both broadcast and keyed state, without luck so far.
