Datafile class models a Cluster Disk Data
datafile, which is used to store Disk Data table data.
Currently, only unindexed column data can be stored on disk. Indexes and indexed columns are stored in memory.
MySQL Cluster prior to MySQL 5.1 did not support Disk Data storage
and so did not support datafiles; thus the
Datafile class is unavailable for NDB API
applications written against these older releases.

||Gets the datafile's object ID|
||Gets the datafile's object status|
||Gets the datafile's object version|
||Gets the file system path to the datafile|
||Gets the size of the datafile|
||Gets the name of the tablespace to which the datafile belongs|
||Gets the ID of the tablespace to which the datafile belongs|
||Sets the Cluster node where the datafile is to be located|
