Administrators should not make any changes when scaled out
If an admin makes any change when scaled out, it will only take effect on one application service/site in real time. The other scaled out sites will not ‘see’ the change until the cache expires on that machine or an action is performed on that machine that causes the cache to clear.
For example, if product inventory is cached for 5 minutes then the longest any machine will have to wait to see updated values is 5 minutes but it could be sooner. Please see Static Cache Guidelines below for information about cache duration.
Some settings, such as Queue-It API key, customer ID, and secret, require an application service restart after any change (whether scaled or not). See Queue-It Release Guide
Customer profile details
If customer profile details are changed in the fulfillment system (RTP|ONE or Siriusware) while the guest is shopping, the changes won’t be seen until the cache is refreshed.
