Feature flags table will be a lot smaller than other tables, writing to it will be performed rarely and only manually (after new release or when we decide to switch a flag). That means that we expect one write per couple of days which makes even the lowest provisioned capacity a couple of orders of magnitude too high for our needs.

Initially, reading is similar: one read per native app start, so at most a couple of reads per hour. In the future, if we decide to change an approach so that we query more frequently, we can change the policy.
