-------------------------------------
Summary: camel-nats - Manual acknowledgement
Key: CAMEL-23483
URL: https://issues.apache.org/jira/browse/CAMEL-23483
Project: Camel
Issue Type: Improvement
Components: camel-nats
Reporter: Michael Weiss
This Ticket was created out of this discussion [#camel > camel-nats - Manual
ACK|https://camel.zulipchat.com/#narrow/channel/257298-camel/topic/camel-nats.20-.20Manual.20ACK/with/594226164]
In Spring RabbitMQ there is a parameter `{{{}acknowledgeMode: MANUAL{}}}` which
allows to manual ack or nack messages, which is actually not possiblem with
camel-nats.
With camel-nats, something like this should also be possible:
{code:java}
from("nats:mySubject?servers=localhost:4222&manualAck=true")
.process(exchange -> {
// do work
doWork(exchange);
// ACK after work succeeds
NatsManualAck manualAck = exchange.getIn()
.getHeader("CamelNatsManualAck", NatsManualAck.class);
manualAck.ack();
}); {code}
With CAMEL-23032 the `{{{}ackPolicy{}}}` was introduced in camel-nats. Maybe we
could add a manual mode there or create a new parameter.
