We use the Beam Java SDK and are trying to upgrade version of Beam from version 2.31.0 to 2.43.0 While upgrading, we noticed that @Nullable annotation has been removed from org.apache.beam.sdk.state.ReadableState.read() I traced it back to this PR: https://github.com/apache/beam/pull/16721 We have the following concerns - If ReadableState.read() is really not nullable, shouldn’t there be a way to specify a default value when creating a state? Such a feature doesn’t seem to exist. - And what would it return initially when nothing is written to the state yet initially? Thank you, Jeeno
