It is a good idea to set up a mechanism that removes markers when they are no longer relevant to your application. You may use markers to monitor some behavior, but once you have gathered the data you need, flush markers from the order in one of the ways described here.

You can either remove specific markers individually, or remove all markers at once. If you want to remove markers from all orders or commerce items simultaneously, invoke the deleteMarkers method on the atg.markers.OrderMarkerManager or CommerceItemMarkerManager class. See the ATG Platform API Reference for more information.
