That is the documentation for (master-slave) replication of a MySQL Cluster (NDB). I am talking about NDB itself. I believe it still is true that MySQL Cluster is main-memory and does not have local storage nor supports a spill to disk scenario that allows for a database larger then main-memory. Together with the lack of durable commits that makes for very specialized use-cases. > How hard is it to port a MS SQL db over? Depends on which features were used. On your schema level you need to convert all your datetime types and redo your full text indexing. You want to make all your strings TEXT (unless you have a specific reason to want them shorter) ad have a good read to see which more exotic datatypes can be useful. For your queries everything with datetimes and uppercase/lowercase needs to be redone and you need to rewrite all your UDFs and stored procedures. Start all performance tuning from scratch as well. I am not familiar with any tools for porting from MS SQL Server.
