Dynamic New Entity id for name_mappings

[YatinArora-NEC]

Hi

I am using Cygnus-1.7.1 and i am using name mapping feature in order to shorten the collection name . I want the new Entity id should be dynamic as per the old Entity id.

The name mapping configuration is as follows:

 {
  "serviceMappings": [
    {
      "originalService": "(.+)",
      "servicePathMappings": [
        {
          "originalServicePath": "/(.+)",
          "entityMappings": [
            {
              "originalEntityId": "ReserveWaterLevel.(.+)",
              "originalEntityType": "WaterSystem",
              "newEntityId": "WaterLevel",
              "attributeMappings": []
            }
          ]
        }
      ]
    }
  ]
}

In the above configuration i am trying to make generic new EntityId that is whenever ReserveWaterLevel.1 comes it should be mapped with WaterLevel.1 ,similarly whenever ReserveWaterLevel.2 comes it should be mapped with WaterLevel.2 in a single mapping.

Anyone can suggest me how can I approach further.

Your Cygnus version (1.7.1) is pretty old. Current one is 1.17.0 and the namemappings functionality has been improved in the meanwhile. Maybe the issue you have could have been solved.

Could you upgrade to Cygnus 1.17.0 and test again, please?

@YatinArora-NEC there are some examples in documentation maybe could help you.

You can write "newEntityId": "WaterLevel$1" to refer to the first result of previous regular expression (...)
