I'm concerned most about postfix reloads. I have a small system only 4
users. (Retired Hobby)
I average nearly 500 failed login attempts from around the world every
24 hours.
Fail2ban sees errors and I add the ip to posctscreen.cidr or nftables
depending, but then I do a reload.
Nftables offers an "atomic" reload. I use MariaDB for the virtual user
info. I wondered if maps or cdir
could read be read from it and eliminate the reload. Maybe a way to do a
map read while still in process?

What is the recommended way to use make map?
It really depends on the use case. That determines the query load,
how often data needs to change, if it needs to be be accessible by
multiple Postfixes, what latencies you can tolerate, and so on.
Also is MariaDB really that much better?
That is difficult to answer without context.
