Set the property bag representing the runtime configuration parameters for this crawler. The runtime configuration would include such settings as a number of threads that a crawler uses to fetch URL, a number of threads used to index cards, etc. Since the crawling algorithm/design is constantly evolving, it is appropriate to have a generic bag to store the config values. This way new crawl algorithm tuning knobs can be added with mimimal modifications to the crawler model.
