Performance Schema NDB Cluster Tables reconciled without manual intervention; these objects are blocklisted and not considered again for mismatch detection until this has been done. The  ndb_sync_pending_objects  and  ndb_sync_excluded_objects  tables are present only if MySQL has support enabled for the  NDBCLUSTER  storage engine. These tables are described in more detail in the following two sections. This table provides information about  NDB  database objects for which mismatches have been detected and which are waiting to be synchronized between the  NDB  dictionary and the MySQL data dictionary. Example information about  NDB  database objects awaiting synchronization: The  ndb_sync_pending_objects  table has these columns: The  ndb_sync_pending_objects  table was added in NDB 8.0.21. This table provides information about  NDB  database objects which cannot be automatically synchronized between NDB Cluster’s dictionary and the MySQL data dictionary. Example information about  NDB  database objects which cannot be synchronized with the MySQL data dictionary: 5020 27.12.12.1 The ndb_sync_pending_objects Table 27.12.12.2 The ndb_sync_excluded_objects Table mysql>  SELECT * FROM performance_schema.ndb_sync_pending_objects; +-------------+------+----------------+ | SCHEMA_NAME | NAME | TYPE | +-------------+------+----------------+ | NULL | lg1 | LOGFILE GROUP | | NULL | ts1 | TABLESPACE | | db1 | NULL | SCHEMA | | test | t1 | TABLE | | test | t2 | TABLE | | test | t3 | TABLE | +-------------+------+----------------+ mysql>  SELECT * FROM performance_schema.ndb_sync_excluded_objects\G *************************** 1. row *************************** SCHEMA_NAME: NULL NAME: lg1 TYPE: LOGFILE GROUP REASON: Injected failure *************************** 2. row *************************** SCHEMA_NAME: NULL NAME: ts1 TYPE: TABLESPACE REASON: Injected failure *************************** 3. row *************************** SCHEMA_NAME: db1 NAME: NULL TYPE: SCHEMA • SCHEMA_NAME : The name of the schema (database) in which the object awaiting synchronization resides; this is  NULL  for tablespaces and log file groups • NAME : The name of the object awaiting synchronization; this is  NULL  if the object is a schema • TYPE : The type of the object awaiting synchronization; this is one of  LOGFILE GROUP ,  TABLESPACE , SCHEMA , or  TABLE
