-Please note that PersistentCacheDirectory (or cache file) is not deleted in any case. For example, consider the case when a kubernetes pod is

+Please ensure that the cache file is not lost or deleted in any case. For example, consider the case when a kubernetes pod is restarted and the cache file (appconfiguration.json) was stored in ephemeral volume of the pod. As pod gets restarted, kubernetes destroys the ephermal volume in the pod, as a result the cache file gets deleted. So, make sure that the cache file created by the SDK is always stored in persistent volume by providing the correct absolute path of the persistent directory.
