Sounds like a reasonable step forward.
Just one question: do we have any data about the performance difference?
Will it be slower for non-HA use cases?
Thanks,

Hi All,
I am proposing to enable Ratis by default on Ozone Manager - HDDS-4498
<https://issues.apache.org/jira/browse/HDDS-4498>.
Ratis on OM has been tested extensively and is stable now.
HDDS-4330 is an on-going effort to support bootstrapping a new OM node. The
pre-requirement for bootstrapping a new OM node is that the cluster must have
ratis enabled OM. This also the pre-requirement for enabling OM HA. Hence, by
enabling ratis by default, we get rid of one extra step in enabling HA.
It is simple to upgrade an existing non-ratis cluster to ratis enabled cluster
- set ozone.om.ratis.enabled to true and restart the OM.
Thanks
Hanisha
