> Now we are nesting DefaultWALProvider inside RegionGroupingProvider, which makes the
logic ambiguous since a "provider" itself should provide logs. Suggest to directly instantiate
FSHlog in RegionGroupingProvider.
> W.r.t wal group name, now in RegionGroupingProvider it's using sth like "<factoryId>\-null\-<randomUUID>"
which is quite long and unnecessary. Suggest to directly use "<providerId>.<groupName>".
> For more details, please refer to the initial patch.
