# After calling 'configure', the gem loads all relevant GTFS info into a database.
# This may take some time (up to a minute) depending on the size of the input data.
# By default, gtfs-realtime uses an in-memory database, which requires reloading all
# data from scratch on each launch. If you'd like to use a persistent database instead,
# set 'config.database_url' above, and include a scheme/protocol path for the DB type
# that you would like to use. gtfs-realtime will generate the relevant tables.
