The following sections provide information about
INFORMATION_SCHEMA tables which are specific to
NDB Cluster. The
FILES table was added
in MySQL Server 5.1.6 as part of NDB Cluster data-on-disk support
(it is available in standard MySQL 5.5 but is not used there). The
was added as part of additions made to NDB Cluster's
ndbinfo information database in
MySQL NDB Cluster 7.2.2; it is implemented as an
INFORMATION_SCHEMA plugin available only in NDB
Cluster binaries or source, and does not exist in MySQL Server 5.5.
Additional statistical and other data about NDB Cluster
transactions, operations, threads, blocks, and other aspects of
performance can be obtained from the tables in the
ndbinfo database. Information
about these tables, see Section 18.5.10, “ndbinfo: The NDB Cluster Information Database”.
