Unfortunately no - mysql itself recommends even with a small amount of data
at least
16GB RAM, but we calculated that it will run with 4GB in our case, but that
is the
limit we have to support to the domain!

Urgh, that is realy 'evil' and I don't think that this will lead to a stable
mysql
cluster node instead I remeber that mysql cluster nodes takes all memory he
can get
as buffer, so if you size this down that heavily, the cluster node will
probably
die!

:-) Sorry, but I think this is no alternative for me.
