[rabbitmq-discuss] Undocumented "original-expiration" value in "x-death" array header

[Thomas Riccardi]

Hi,

When using the dead lettering feature the rabbitmq broker (v3.2.4) adds
a "x-death" array header, and its values are documented here:
http://www.rabbitmq.com/dlx.html

queue, reason, time, exchange and routing-keys.

However, when using per-message TTL (not per-queue message TTL), there
is an additional string value: "original-expiration", which contains the
expiration property of the original message.


This value probably doesn't appear when no expiration was set in the
original message; so there may be other optional properties of the
original message that are forwarded in the x-death array and not
documented either.

The documentation should be updated to include all of this.


Thanks,
Thomas
