MySQL 5.7 Reference Manual  /  ...  /  INFORMATION_SCHEMA Tables for MySQL Cluster

19.5.11 INFORMATION_SCHEMA Tables for MySQL Cluster

Two INFORMATION_SCHEMA tables provide information that is of particular use when managing a MySQL Cluster. The FILES table provides information about MySQL Cluster Disk Data files. The ndb_transid_mysql_connection_map table provides a mapping between transactions, transaction coordinators, and API nodes.

Additional statistical and other data about MySQL 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 19.5.10, “The ndbinfo MySQL Cluster Information Database”.
