now we can run multiple lbs in the same 'cluster' and they will all point to
the same nodes. all lb nodes are not guaranteed to have the same set of
functions nodes to route to at any point in time since each lb node will
perform its own health checks independently, but they will all be backed by
the same list from the db to health check at least. in cases where there will
be more than a few lbs we can rethink this strategy, we mostly need to back
the lbs with a db so that they persist nodes and remain fault tolerant in that
sense. the strategy of independent health checks is useful to reduce thrashing
the db during network partitions between lb and fn pairs. it would be nice to
have gossip health checking to reduce network traffic, but this works too, and
we'll need to seed any gossip protocol with a list from a db anyway.
db_url is the same format as what functions takes. i don't have env vars set
up for fnlb right now (low hanging fruit), the flag is `-db`, it defaults to
in memory sqlite3 so nodes will be forgotten between reboots. used the sqlx
stuff, decided not to put the lb stuff in the datastore stuff as this was easy
enough to just add here to get the sugar, and avoid bloating the datastore
interface. the tables won't collide, so can just use same pg/mysql as what the
fn servers are running in prod even, db load is low from lb (1 call every 1s
per lb).
i need to add some tests, touch testing worked as expected.
