+        // 
+        // NOTES: Archiving logic can be generalized as follows:
+        // 0) Do SQL query over log_link_visit_action & join on log_action to select
+        //    some metrics (like visits, hits, etc.)
+        // 1) For each row, cache the action row & metrics. (This is done by
+        //    updateActionsTableWithRowQuery for result set rows that have 
+        //    name & type columns.)
+        // 2) Do other SQL queries for metrics we can't put in the first query (like
+        //    entry visits, exit vists, etc.) w/o joining log_action.
+        // 3) For each row, find the cached row by idaction & add the new metrics to
