Sorry for the late reply.
I'd second that. I was just on the Solutions Linux in Paris and spoke
with MySQL people.
There were some questions I had around the new NDB cluster tables and I
stopped by at their booth. My question if there are any plans to add
foreign key support to NDB cluster tables got answered with "it will
definitely be in the next version, which is the one containing NDB
cluster, so yes, it will support foreign key from the start".
Back home I found some more time to investigate and found this forum
article http://lists.mysql.com/cluster/1442 posted by a MySQL AB senior
software architect, where he says exactly the opposite.
I don't know about your application, but trust me that maintaining
proper referential integrity on the application level against a
multimaster clustered database isn't that easy. So this is in fact a
very important question.
