wuzhiguo commented on ATLAS-4485:
---------------------------------
[~sarath] I found the reason why atlas cannot support read replicas is
`AtlasTypeRegistry.registryData` cache(or something else I have missed). What
if we move the cache to redis?
> Can HA support multi write/read?

> Project: Atlas
> Issue Type: Improvement
> Components: atlas-core
> Affects Versions: 2.2.0
> Reporter: wuzhiguo
> Priority: Major
> Labels: features, performance

> Currently HA is like a backup mode, the write/read operation can only go
> through main instance, If main instance crashed because of sudden increase in
> traffic, the backup instance will meet same problem.
