Description

ApplicationID is used to identify an application across many job submissions (for example after restoring from a savepoint). This is currently exposed in the Environment, which might be unnecessary.

State backends, which need the ID can generate it themselves and store it as part of their state handle.

This has to be checked with the DB state backend, which currently uses this.
