AFAIK, you can put any kind of map file in $mydestination - e.g. you can
use a hashed db.
you can certainly do it for $virtual_maps, which is probably what you
want rather than $mydestination.

you should be able to use an LDAP map too. a hashed db would be faster.
generate the map from the source data extracted from an LDAP database if
BTW, for large map files, create them with a temporary filename and then
mv them into place. creating a hashed file takes a significant amount of
time, but mv is atomic.
