Batching/Convoy without Correlation?
|

| Hi,
I want to implement a convoy pattern for the purpose of
batching up a bunch of messages and then sending the
batched message to an external vendor. The problem is
that I don't have anything good to correlate on.
Meaning, when the receive location receives the files to
batch, they are unique. Every file that comes into that
receive location needs to be put in a batch. They
represent a common theme, like ordering an item, but I
don't want to batch based on id's, etc... The examples I
keep finding have things like SupplierId, Stock Ticker,
etc... So, for example, I would want to batch a BUNCH of
messages together for a BUNCH of stock tickers, not just
one stock ticker.
Once a certain amount of time has elapsed or a certain
number of items have been batched then I want to post the
batch to the vendor. This part I have figured out. But
how can I get my orchestration configured to do what I
want it to do? One thought I had was to force a value
into the schema that is generic (like "UPDATE") and
promote it and use that in the correlation set but I
don't want to mess with the schema if I don't have to.
Any suggestions are appreciated in advance!
Thanks,
Michael

| You could correlate on receive port name if that works for you.

| Matt,
Thank you for your input. I found one that seems to be
working: BTS.MessageType
Since all the messages arriving on that port are the same
type then I am going to give that a shot. Let me know if
you see something wrong with this approach.
I suffered from tunnel vision and was worrying about the
correlated property coming from the XML message itself
and didn't think about all the other types I could
correlate on!
Regards,
Michael
