Hi @Thxzzzzz , thanks for the Pull Request! I'd be fine with the feature - but I have some concerns on the implementation - see comments. :+1:

@Thxzzzzz mind checking out https://github.com/yannh/redis-dump-go/pull/14 ? I am looking for something more explicit than -km, though I m not sure it's great :) Note that some of the code is taken from an older version from redis-dump-go, since this is how it worked before it was changed to use Scan instead - which is more consistent and less memory intensive.

noscan is better then -km. but i think there are too many params on function DumpDB and DumpServer , maybe replace it with a struct or functional options pattern?

Yep, that would be a nice improvement.. I ll merge this for now, might refactor later! Thanks!
