tpt export import

I have been doing teradata export and import through named pipe until i used tpt. But now after i learnt how to write a tpt, i have been using import from export operator in tpt. I have used it but unfortunately, i could not find much information on how and where the data is stored intermitently after export is done before it is imported using a load/update operators.

can someone please help me find this information or provide inputs on this?

Thank you for trying TPT. I think you will find it easier to do export-to-load with TPT than trying to use FastExport and FastLoad (or MultiLoad) with named pipes and all of the coordination needed.

TPT uses shared memory to pass the data buffers from the "producer" operators (i.e. Export operator) to the "consumer" operators (i.e. Load or Update operator).

We do not use named pipes and we do not use intermediate disk storage. And the export and load is taking place in parallel at the same time. They are not sequential operations.

Feinholz,

Where does this shared memory exist? on the file system?

We use the system's virtual memory. We do not use a file system.
