Is it possible to have HA group with one primary and multiple standby nodes ?
I see documentation shows only 3 node configuration(1 primary, 1 secondary and 1 monitoring node)
@rdesoju You almost answered your own question
DMR is effectively MNR for guaranteed messaging. MNR only supports DIRECT delivery mode ("fire and forget," "reliable," or "pure pub/sub"), with which there is no persistence.
If you have DMR between triplets then yes, you have Guaranteed Messaging between triplets. In this way you form a cluster of triplets, which are linked together, share information on where an application is listening to guaranteed messages, and share these messages appropriately.
Hi @rdesoju, no, our HA configuration only support the triplet configuration: 1 primary, 1 backup and 1 monitor.
Note that we do support multiple HA triplets clustered together - this is our DMR feature.
Thanks for the confirmation.
How DMR (Dynamic message routing) is different from MNR (Multi Node Routing)? I am little confused?
Is Guaranteed messaging supported if we enable DMR between HA triplets?
