Reltio Connect

We have implemented cardinality for all data types including String, Integer, Boolean, Lookup, Reference etc. But this works only for String type and doesn't have effect for any other types.

Is this expected? How to resolve this?

Please let know if we are missing something.

 .

Cardinality should be equality supported regardless of data type.  However, it is only enforced by the Reltio UI.  If you have multiple distinct values arriving from multiple crosswalks with an Aggregation survivorship strategy, it will accept the data with no errors.  If you POST data from a single source which violates the cardinality it will not prevent it - regardless of the data type.  

However, for any record which violates cardinality rules, you will be unable to edit them in the Reltio UI until the issue is resolved.
