> {*}Summary{*}{_}:{_} Initialization of the cluster configuration using meta
> storage revision 0 leads to race conditions, resulting in potential
> misconfiguration.
> {*}Analysis{*}: Currently, the system applies the initial cluster
> configuration locally when the meta-storage revision is at 0. This approach
> can lead to race conditions where the initial configuration might be
> overlooked if the revision number changes during the initialization process.
> _Suggested Fix:_ We should modify the initialization logic to:
> # Use the local revision of the configuration key.
> # If the local revision is absent, only then fall back to the initial
> configuration.
> This approach would prevent the configuration from being ignored due to
> changes in the meta-store revision.
