I was hoping to learn whether or not the underlying read replica instance would be cleaned up after a period of inactivity.As the lifecycle doc explains, if there are no requests handled within a region then after some period the replicas will hibernate or get evicted, and the next requests in that region will have to boot the replica again. Those first requests will be forwarded to the primary until the replica is ready again to serve traffic.
In the future we want to allow dynamic replicas that follow your traffic, but the lifecycle will still exist.
