-// During this operation, the read replica will not be available. Endpoints will not change.
+// When you resync a read replica, first it is reset, and then its data is resynchronized from the primary node.
+// Your read replica will be unavailable during the resync process. The duration of this process is proportional to your Database Instance size.
