The OSM DB update script should add all areas affected by the update to the tilerator job que.
Example Post request:
http://localhost:6535/add ?expdirpath=/srv/osm_expire/ -- expiration files dir &expmask=expire.* -- regex to match expiration files &statefile=/home/yurik/osm_expire.state -- tilerator uses this file to record last imported data file &fromZoom=10 -- new jobs will be created from this zoom &beforeZoom=16 -- and until (but not including) this zoom &generatorId=gen -- copy tiles from ("gen" will only produce non-empty tiles) &storageId=v3 -- copy tiles to &deleteEmpty=1 -- if tile is empty, make sure we don't store it, if it was there before
