Summary: camel-pulsar - Support for delayed delivery pulsar
messages using deliverAt
Key: CAMEL-19210
URL: https://issues.apache.org/jira/browse/CAMEL-19210
Project: Camel
Issue Type: Improvement
Components: camel-pulsar
Reporter: Alastair Burr
Fix For: 3.x
*Description*
Support for delayed delivery pulsar messages using deliverAt
*Proposed change*
To add in the ability to set the delayed delivery of Pulsar messages by use of
a header. This would use the deliverAt() functionality on the Pulsar producer
which simply takes in the a timestamp in milliseconds based on UTC
https://pulsar.apache.org/api/client/2.11.x/org/apache/pulsar/client/api/TypedMessageBuilder.html#deliverAt(long)
*Background:*
Delayed delivery is a very useful feature within Pulsar that can be used for a
number of scenarios where you want the message to be picked up at a particular
time.
There is additionally a deliverAfter() method on the Pulsar producer where you
can specify a time period instead of a specific time, but the implementation
behind the scenes just turns this into a timestamp then uses that. As such just
implementing deliverAt() provides enough flexibility to the clients.
