So yeah /normally/
you hit DB servers at random and different servers might respond
differently (or be lagged to different degrees), but in this
particular case it was always the same DB server returning the same
lag value. Nothing strange going on here, this is how the maxlag
parameter works.
How do you feel about a switch to change that behavior (maxlag - 1)? It
would be nice to be continue guiding developers towards throttling API
requests around maxlag without complicating schema migrations by
requiring
config deployments before and after every db for this reason only.
Why don't we have a system to allow databases to be automatically taken
out of the LB temporarily?
