Key: GEARPUMP-78
URL: https://issues.apache.org/jira/browse/GEARPUMP-78
Project: Apache Gearpump
Issue Type: Improvement
Components: streaming
Reporter: Manu Zhang

DAG with loop should not be called DAG :)
We see use cases that require a feedback channel.
The challengues will be:
# how to support the low watermark clock? As the clock is defined recursively?
# How to support back-pressure. DAG with loop can possiblely create a live-lock
issue. With each processor wait for acks from other processor before sending
acks.
