Arpit Agarwal commented on HDDS-759:
------------------------------------
I strongly dislike adding more config settings but in this case it is necessary
to allow customization for performance reasons.
For most production clusters, admins will want to carefully choose where they
place OM and SCM metadata, similar to how they choose locations for NN metadata.
> Create config settings for SCM and OM DB directories

> Priority: Major

> Currently SCM, OM and DN all use {{ozone.metadata.dirs}} for storing metadata.
> Looking more closely, it appears that SCM and OM have no option to choose
> separate locations. We should provide custom config settings.
> To avoid disruption, we can have them fallback to {{ozone.metadata.dirs}}.
