Diskless

Quote:

It is possible to specify MySQL Cluster tables as diskless, meaning that tables are not checkpointed to disk and that no logging occurs. Such tables exist only in main memory. A consequence of using diskless tables is that neither the tables nor the records in those tables survive a crash. However, when operating in diskless mode, it is possible to run ndbd on a diskless computer.

Important: This feature causes the entire cluster to operate in diskless mode.

When this feature is enabled, backups are performed but backup data is not actually stored.

Correctly last sentence should state something like:

When this feature is enabled, the ndb online backup feature is disabled.  Moreover partial start of the cluster is not possible.

How to repeat:
