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:

table has these columns:
SCHEMA_NAME: The name of the schema
(database) in which the object which has failed to
synchronize resides; this is NULL for
tablespaces and log file groups

failed to synchronize; this is NULL if
the object is a schema
TYPE: The type of the object has failed
to synchronize; this is one of LOGFILE
GROUP, TABLESPACE,
SCHEMA, or TABLE
REASON: The reason for exclusion
(blocklisting) of the object; that is, the reason for the
failure to synchronize this object
Possible reasons include the following:
Injected failure
Failed to determine if object existed in

Failed to drop object in DD
Failed to get undofiles assigned to logfile
group
Failed to get object id and version
Failed to install object in DD
Failed to get datafiles assigned to
tablespace
Failed to create schema
Failed to determine if object was a local
table
Failed to invalidate table
references
Failed to set database name of NDB
object
Failed to get extra metadata of
table
Failed to migrate table with extra metadata
