Re: Mysql cluster NDB 7.4.11 disk data storage strange behavior

1M is not realistic for data memory or index memory. There is always going to be some overhead. There are NDB system tables required for operation and other factors--for example, every NDB table has an implicit ("hidden") primary key.

The fact that the cluster is using some memory has no relation to whether or not it is storing the data on disk. For that information, you should examine the INFORMATION_SCHEMA.FILES table. (Make sure you're checking the NDB section and not the InnoDB section.) There are some example queries there to help you.

cheers,
