Explanation
This rule counts the number of metadata elements in one aggregate and reports back an issue when the configured maximum number of metadata elements is exceeded. It is recommended for performance issues, to keep the number of metadata elements in the aggregates below this maximum, otherwise this could cause performance issues in your application.
Parameter
maxElements | By default the metadata elements in the aggregate rule applies a maximum of ten. By changing this parameter, the maximum threshold value can be increased or decreased. Default Value: 10 |
Possible improvement
Try to use only metadata in your aggregates that are really necessary.
Example
