2969041 - CCv2 - Web Cache on storefront endpoints

Symptom

Web Cache on storefront endpoints is implemented as Apache mod_proxy with allocated 5Gi disk space,

HTCACHECLEAN_SIZE set to 4Gi and HTCACHECLEAN_DAEMON_INTERVAL set to 120 minutes.

So, if you will enable Web Cache, it could happen in your kubernetes cluster that:

  • Apache pod could be Evicted because: - no space for cache when you will want to cache too many medias in short period of time
                                                                 - IOPS limit reached on Azure side during cleaning of old medias from cache disk
  • other pods which will be on same VM as Apache could be Evicted too and restarted
