Yes we should add it.


The notification topic name can be changed after the creation of the feature group.
By setting the `notification_topic_name` value to `None` or empty string notification will be disabled.
With the default configuration, it can take up to 30 minutes for these changes to take place since the onlinefs service internally caches feature groups.

in onlinefs it is set like this: .expireAfterAccess(30, TimeUnit.MINUTES)
so user would not be able to change it (same for all cached entries), should we enable user changing this value?

also it might be better to change them from expireAfterAccess (this includes last access, so if user constantly writes it might not expire ever) to expireAfterWrite

Yeah It should be a configurable parameter.
