We are currently using a full version of Ignition running on a server that controls and records data from multiple machines. In order to improve system reliability we are considering utilizing edge instances at each machine. However, we currently use transaction groups to record formatted tag data to a database every few minutes. We use this data for our process records.
In the case of a network related failure, we understand that the store and forward would allow the tag history for the edge instance to be retained and sent to the server once the connection is remade.
However, how would we backfill/reconstruct the missing process data that would normally be recorded via the transaction groups?
