Hi Murtaza,

I think there might be a misunderstanding here. It is possible to write in parallel from many
MySQL Servers already in 4.1. The problem with only writing from 1 server was when you are
using MySQL Replication for clustered data. This problem is solved in MySQL 5.1 but parallel
writes to the cluster has been possible since version 0.1 of the cluster part so this has always
been there.
