[Question] state scope to only key

[Vignesh Kumar Kathiresan via user]

Hi Community,

I am new to beam coming from flink. In flink state can be scoped to only
key. A datasteam(similar to Pcollections in beam) can be converted to a
keyed data stream. And a process function on this keyed stream can access
state scoped to only key. It also has state scoped to key+window. In beam
though I see only state scoped to key+window combination. Is my
understanding correct? How are use cases using state scoped to key without
windows solved in beam.

thanks
