The way N8N works with Rabbit MAQ is not statisfying for me.
The purpose here is to be able to limit the number of simultaneous workflow from unknow number of simultaneous event.
DB Stack_Pim must have a field to store the process status and a record key to be transmetted to the processing workflow
process_status : null/processing/processed
http request send the DB record key
For test purpose, a simple workflow to wait few secondes. The last step update DB stack_pim process_status=“processed” on the DB record receive by the webhook.
Et voila ! hope its help.
