General question around Atlas Service HA fixes and atlasclient

[fortm]

Using this client , we can send requests to ATLAS service.

It seems only 1 instance of Atlas Service(containing kafka consumers + REST API + in-memory typed cache ) runs at any point.
But lately they have done similar to Namenode in Hadoop federation kind of setup with option to run it in High Availability mode under ATLAS-510.

Can we use atlasclient latest version on fixed version of Apache Service for ATLAS-510 + ATLAS-488 ?

Atlas Service Scalability:
https://issues.apache.org/jira/browse/ATLAS-488

High Availability:
https://issues.apache.org/jira/browse/ATLAS-510

Also had a doubt, if the atlasclient helps in resolving some of multi-tenancy issues reported in ATLAS-510 ?

Multi-tenancy: Open
https://issues.apache.org/jira/browse/ATLAS-510

Finally, can we run multiple instances of Atlas Service with only REST-API(s) or only kafka consumers ? This is however not related to atlasClient.

Unable to scale multi-consumers: Open
https://issues.apache.org/jira/browse/ATLAS-3305

Thanks
