Every 3.5 minutes, LCE will:
read in the results of the last-executed action, from
choose the next action to take based on the last-executed action
perform the next action and store results in
Storing the state in this manner has the following advantages:
simplicity (no separate logic to handle reloads/restarts is needed)
transparency (to see exactly where the archival algorithm is, just query
available emergency override (can alter the control flow by updating lce_status.db)Note: This is not standard operating procedure and should only be performed in very rare cases.
