question about READ COMMITTED isolation level (no replies)

Hello folks,

I am new in MySQL cluster although I have some experiences with InnoDB. What is bugging me now is NDB engine doesn't support MVCC. So that means it doesn't support consistent nonlocking read, right? So does it acquire a lock before reading a row? I can't find anything in the docs, it seems everything relevant to READ COMMITTED isolation level is about InnoDB. Could anyone please point me to the right material?

Jim
