MySQL 8.3 Reference Manual  /  ...  /  INFORMATION_SCHEMA Tables for NDB Cluster

25.6.18 INFORMATION_SCHEMA Tables for NDB Cluster

Two INFORMATION_SCHEMA tables provide information that is of particular use when managing an NDB Cluster. The FILES table provides information about NDB Cluster Disk Data files (see Section 25.6.11.1, “NDB Cluster Disk Data Objects”). The ndb_transid_mysql_connection_map table provides a mapping between transactions, transaction coordinators, and API nodes.

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. For information about these tables, see Section 25.6.17, “ndbinfo: The NDB Cluster Information Database”.
