performance: tcl proc vs xlt+variant

[Yves Guerin]

Hello,

I am wondering which solution is the best regarding the performance (cpu friendly)

Task to do: delete the DG1 segment in A01,A08,A011 but I got the A03 too (who do not contain the DG1 segment)

Solution-1: tcl proc in the inbound thread

   – pros:

        — the tcl interpet will compile the tcl proc so I will gain time

   – cons:

       — parse the message, remove the DG1 segment and rebuild the new message

       — waste time on the A03

Solution-2: create a variant and remove the DG1 segment, I do a bulkcopy on top on my xlate

   – pros:

       — do not manage the trouble to remove the segment, the variant will do it for me

       — no waste of time for the A03

   – cons:

       — ?

thank you in advance your help

It is my understanding that the Xlates run tcl in the background to perform their functions.  If this is the case, I really see no difference one way or another.

My preference would be to do this in an xlate.  It is much simpler.   All you need to do is have an IF statement.   If the message is an A01, A08, or A11, simply do a Pathcopy of @null to the DG1 segment.

Hope this helps…

Hello,

Thank you for your answer. I use the bulkcopy, like this, I do not have to care about the segments.  I did a xlate for each message anyway (I have to: from 2.3 to 2.2) so I let the xlate thread to handle this kind of problem, and I think (I do not know what happen behind the scene) it is more efficient than the inbound proc.  May be I am wrong ?!

I too use the Xlate.

Slight difference – I do not use BULKCOPY – so all I need to do if the receiving system indicates they do not support certain segments is I simply don’t COPY or PATHCOPY that segment.

Hello,

💡 Great idea to put on the hl7 message, the information about the delete operation to perform.

I use this kind of manipulation to do the routing for my tagging system 😉

A point about manipulating a message at the Inbound Tps UPoC – whatever changes you make to a message at that UPoC will be effective for EVERY receiving system – even future receiving systems you do not even know about yet.

If I am going to use Tcl to manipulate a message I tend to do it at the Route (Pre-Xlate typically). That way I can control what effects happen per receiver.
