> Users such as Ozone may archive part of their data and mark it immutable. In
> Ozone, closed containers use a synthetic read pipeline whose ID does not
> correspond to a live Ratis group, causing DataStream reads to fail with
> {{{}GroupMismatchException{}}}. {{DataStreamReadResolver}} should provide an
> optional path to bypass group lookup and let the application define how such
> reads are handled. If the resolver declines the request, the existing Ratis
> read path remains unchanged.
