Some database objects such as tables and indexes have different
limitations when using the
NDBCLUSTER storage engine:
Database and table names.
When using the
NDB storage engine, the
maximum allowed length both for database names and for
table names is 63 characters.
In MySQL Cluster NDB 7.3.8 and later, a statement using a database name or table name longer than this limit fails with an appropriate error. (Bug #19550973)
Number of database objects.
The maximum number of all
NDB database objects in a
single MySQL Cluster—including databases, tables,
and indexes—is limited to 20320.
Attributes per table. The maximum number of attributes (that is, columns and indexes) that can belong to a given table is 512.
Attributes per key. The maximum number of attributes per key is 32.
