index. To prevent this, you must specify the
The default value is 64. Each index consumes approximately 15KB per node.

MaxNoOfTriggers
Effective Version
MySQL 5.0.0
Restart Type: N
Internal update, insert, and delete triggers are allocated for each unique hash index. (This means
that three triggers are created for each unique hash index.) However, an ordered index requires only

This parameter sets the maximum number of trigger objects in the cluster.
The default value is 768.

MaxNoOfIndexes
This parameter is deprecated. You should use
