Hi All,
I have an input of fixed length format and my output required is also a fixed length with one to one mapping and all feilds in input is not required on output.Can i just use a mapping node and route the message to the output.
Is there any advantage of using compute node over mapping node.And can Mapping node handle all types of inputs(xml,tds,fixed).
All replys and comments are appreciated.Thanks. |

If both input and output are defined by message sets (which they should be in the case you give)

A Mapping node can handle any message for which a message set can be generated.
Compute nodes allow for the easier development of more complex transformations, and access to external data sources, etc, etc, etc. Which has "the advantage" depends entirely on your requirements.

In our experience we have found maintainence to be much easier when using ESQL instead of a mapping node.
Our first project had mapping nodes in it and we got sick of trying to do maintainence on the mapping nodes. Now all of our mapping is done in ESQL.
All of the code is right there in the file, easy to see and follow. For the mapping node you need to click open each field to see what is being done for that field. That gets old, really quick. |

One point in favour of the Mapping node. If your output message definition is similar to the input message definition, you will be able to exploit the 'Map by name' feature, which works beautifully and can save a lot of time,
Horses for courses...choose the one which best fits the problem. |

Compute Node is better in performance than Mapping Node.

One can modify the headers (if need be) in compute node and not in mapping node...

It depends - In V6, you can map and modify the headers.
