BACKPRESSURE-EDI

Backpressure in EDI pipelines. See Enterprise Integration Patterns.

Definition

Backpressure — mechanism by which a downstream node signals to an upstream node that it can no longer absorb messages at the current rate; the upstream slows down, buffers or rejects.

Origin

Pattern documented in streaming (Reactive Streams, Akka, Kafka). Adapted to EDI where a partner can only process a given AS2/SFTP throughput; rate limits are usually expressed in messages per minute.

Use

When an AS2 partner rate-limits at 30 MDN/minute, the local gateway applies backpressure: the queue grows, SRE alerts fire above a threshold, and delayed MDNs do not trigger premature retransmissions.
