How to split a message into chunks in a file to proxy interface

Hi, all

We have an file to proxy async interface. The content of the file is straight forward but with 400K lines and 50M in size. Each line is a record. Is there a way to split the file into multiple chunks and send the receiver system(ECC) multiple messages. Since there is no sequencing in the data, we can process the data in parallel in ECC if possible.

There is a feature called chunkmode for the file adapter. However, it seems to me that the receiver needs to be file adapter too. It also do a file combination in the end which is not what I want. I also tried the "recordsets per message" and it seems to do a combine when the message gets to the receiver.

Can you please advise?

Thanks,

Jonathan.
