Can NCo 3.0 retrieve a million records?


I have a custom ABAP module that sometimes returns million+ records. With NCo 2.0, this was not directly possible as the connector would try to get all the records at once in memory. Fortunately, NCo 2.0 supported a mechanism to get the data as callback (using DESTINATION CALLBACK in my ABAP code). Thus, my ABAP code can keep sending the data on my callback until all the records are exhausted.

Now, I am moving my .NET code from NCo 2.0 to NCo 3.0. As I understand, there is no support for "DESTINATION BACK" in NCo 3.0. This is not an issue for me as long as the new NCo 3.0 mechanism can handle returning million+ records. This can happen only if the connector streams records and not try to build the whole resulting table in memory.

So, does NCo 3.0 try to get the records as a network stream or fill the whole structure of records in memory as NCo 2.0 used to do?

Thank you in advance for your help.
