NDB Cluster Configuration Files Assuming that you can create all desired tables without any problems, you should also verify that this number is sufficient by trying an actual  ALTER TABLE  after configuring the parameter. If this is not successful, increase  MaxNoOfAttributes  by another multiple of  MaxNoOfTables  and test it again. A table object is allocated for each table and for each unique hash index in the cluster. This parameter sets a suggested maximum number of table objects for the cluster as a whole; like MaxNoOfAttributes , it is not intended to function as a hard upper limit. (In older NDB Cluster releases, this parameter was sometimes treated as a hard limit for certain operations. This caused problems with NDB Cluster Replication, when it was possible to create more tables than could be replicated, and sometimes led to confusion when it was possible [or not possible, depending on the circumstances] to create more than  MaxNoOfTables  tables.) For each attribute that has a  BLOB  data type an extra table is used to store most of the  BLOB  data. These tables also must be taken into account when defining the total number of tables. The default value of this parameter is 128. The minimum is 8 and the maximum is 20320. Each table object consumes approximately 20KB per node. For each ordered index in the cluster, an object is allocated describing what is being indexed and its storage segments. By default, each index so defined also defines an ordered index. Each unique index and primary key has both an ordered index and a hash index.  MaxNoOfOrderedIndexes  sets the total number of ordered indexes that can be in use in the system at any one time. The default value of this parameter is 128. Each index object consumes approximately 10KB of data per node. Note The sum of  MaxNoOfTables ,  MaxNoOfOrderedIndexes , and MaxNoOfUniqueHashIndexes  must not exceed  2$^{32}$  −  2  (4294967294). 4096 • MaxNoOfOrderedIndexes Version (or later) NDB 8.0.13 Type or units integer Default 128 Range 0 - 4294967039 (0xFFFFFEFF) Restart Type N (NDB 8.0.13) Note The sum of  MaxNoOfTables ,  MaxNoOfOrderedIndexes , and MaxNoOfUniqueHashIndexes  must not exceed  2$^{32}$  −  2  (4294967294).
