SHOW Statements • NdbIndexOperation : The number and size of  NdbIndexOperation  objects that have been created. • NdbRecAttr : The number and size of  NdbRecAttr  objects that have been created. In general, one of these is created each time a data manipulation statement is performed by an SQL node. • NdbBlob : The number and size of  NdbBlob  objects that have been created. An  NdbBlob  is created for each new operation involving a  BLOB  column in an  NDB  table. • NdbReceiver : The number and size of any  NdbReceiver  object that have been created. The number in the  created  column is the same as the number of data nodes in the cluster to which the MySQL server has connected. Note SHOW ENGINE NDB STATUS  returns an empty result if no operations involving NDB  tables have been performed during the current session by the MySQL client accessing the SQL node on which this statement is run. 13.7.7.16 SHOW ENGINES Statement SHOW [STORAGE] ENGINES SHOW ENGINES  displays status information about the server’s storage engines.
