This setting can be used to optimize externallinks queries for certain domains that have many entries in the externallinks table, but also big “gaps” where the table contains no entries for that domain. By putting those gaps (whose el_id values would usually have been obtained on the analytics databases) into the configuration, we can have MediaWiki tell the database to skip those ranges of the table instead of scanning through them. (This is only relevant for domains that have enough entries that the database chooses to scan the table in primary key order rather than using the el_to_domain_index_to_path index and filesorting.)
