Work Description: lavocatt opened a new pull request, #5220:
URL: https://github.com/apache/activemq-artemis/pull/5220
Add a new option in the Mirror setting to prevent a broker from propagating
messages.
When working with a topology where 4 nodes form a square and each node
mirrors to its two neighbors, a message leaving a corner can reach the opposite
corner of the square by two different routes. This is causing the ordering of
message to get broken.
example:
1 <-> 2
^ ^
| |
v v
4 <-> 3
A message from a will reach 3 by 2 and 4. Message duplication checks will
prevent the message from being duplicated but won't help regarding the order of
the messages.
Using the new option to not forward messages coming from a link, we break
the possibilities to have two routes to reach the opposite corner.
On the example above, we ask 4 to not forward any messages coming from 1 if
1 is the primary sender of the messages.
This means that now, a message sent to 1 will reach 3 only by 2 and not by 4.
