Maximum number of tablespaces: 2³² (4294967296)

Maximum number of data files per tablespace: 2¹⁶ (65536)

Maximum data file size: The theoretical limit is 64G; however, the practical upper limit is 32G. This is equivalent to 32768 extents of 1M each.

Since an NDB Cluster Disk Data table can use at most 1 tablespace, this means that the theoretical upper limit to the amount of data (in bytes) that can be stored on disk by a single NDB table is 32G * 65536 = 2251799813685248, or approximately 2 petabytes.

The theoretical maximum number of extents per tablespace data file is 2¹⁶ (65536); however, for practical purposes, the recommended maximum number of extents per data file is 2¹⁵ (32768).

The minimum and maximum possible sizes of extents for tablespace data files are 32K and 2G, respectively. See Section 13.1.18, “CREATE TABLESPACE Syntax”, for more information.
