Hi,
The documentation says it is a producer property you can set.
“msgTtl
The number of milliseconds before messages are discarded or moved to a Solace-internal Dead Message Queue.”
See - GitHub - SolaceProducts/spring-cloud-stream-binder-solace: Spring Cloud Stream Binder for Solace PubSub+
This sets in on a per producer basis - is this sufficient for you?
Not sure if it can also be set in code somehow.
