Optimize revalidate of feed detail pages #67
Description
In web-app we expose an endpoint 'api/revalidate' which when called will manually invalidate the server side cache. With this endpoint you can invalidate by
all feeds
gbfs feeds
gtfs feeds
gtfs rt feeds
specific feeds (by id)
End goal: Refresh the cached server feeds when there are changes in the feeds
Current scenario
A cron job is run from Vercel once a day which invalidates all cache.
Ideal scenario
We should only invalidate the cache of the feeds that have been updated with the most precision as possible. Ex: If overnight feeds mdb-2, mdb-5, mdb-1992 were updated, only invalidate those
