Hello all,
I would like to setup a DMQ bus where servers can come on and offline and
have DMQ continue working with the online servers. I'm having trouble
understanding how to do that with the notification address. Can someone
point me in the right direction?
More specifically, suppose I have five servers named A, B, C, D, and E. I
would like all of them to be on the DMQ bus when active but they may come
up at different times. For example, when A, B and C start I want each of
them to be on the same DMQ bus. However, the way I understand it, if I
make E the notification address none will be on the bus because E is not
active.
I could create a circular notification chain where A uses B as a
notification server, B uses C, and so on. Of course, there are problems
when one or more servers are missing from the chain.
Any help on this is greatly appreciated.
Thanks,
Bob

Hello Bob,
It is only possible to specify one notification address. So it is important
to make sure it points initially to an active node.
Once it has joined the cluster, the active node list is shared between all
servers, so it should not matter which servers are up or down later.
But for now, the notification address must be active at least on startup.
It seems we may need to add SRV support to the dmq module at some point,
when there is some spare time :-)
Cheers,
Charles

Charles,
I am working with the team that requested the SRV enhancement. I have some
time now to do some coding and would like to work on a patch to allow
multiple notification addresses. Would you be willing to discuss this? We
can take this conversation offline or move it to SR-Dev if you like.
Thank you for considering this,
Bob

Hi Bob,
Yes, sr-dev would probably be more appropriate. Or if you would like to
send a patch directly or raise a pull request on Github, that would be fine
also.
SRV support is probably the way to go, since adding multiple addresses in
config suggests a prior knowledge of nodes in advance, which doesn't fit
with the DMQ ideology. I did start but got sidetracked with other
commitments, as happens increasingly more often lately!
Cheers,
Charles
