Tracking ticket to improve performance of the _vcaltoservice view.
The view _vcaltoservice expands for each single calendar day, the associated services based on both calendar and calendar_dates. This is necessary as this work needs to be done either way for routing logic (see CSA connections DB query). Perf generally needs to be re-examined for _vcaltoservice as creating this view (and computed table _cvcaltoservice) can be quite a bit slow for certain GTFS archives.
Note: for feeds that have arbitrarily high end_date(s) in the GTFS calendar table, this can dramatically effect performance. E.g. set end_date to 4000 in calendar_dates for example.
