Subject [jira] [Updated] (ACTIVEMQ6-30) allow backup servers to service multiple live servers
Date Wed, 12 Nov 2014 22:43:33 GMT

     [ https://issues.apache.org/jira/browse/ACTIVEMQ6-30?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

clebert suconic updated ACTIVEMQ6-30:
-------------------------------------
    Description: 
On this you could have a number of backup Nodes (M) serving a number of live Nodes (N)

On that scenario you would always have N+M nodes. you would only support M lives failing on
this scenario.

Right now a backup can only support one live. With this we would allow it to serve multiple
lives.

I'm not sure yet if this applies to replication as well. It's easy to be implemented with
shared storage. We will need to investigate if this makes sense with replication or not. (To
be discussed during design discussions before the implementation)


  was:
We called this as N+M Backup with shared storage, but the same policy could be applied with
replication.

You have a few nodes elected to be backups. Say you have for example 3 nodes as dedicated
backups (M) for 10 live nodes (N), resulting in N+M nodes.

We could implement the same using replication? That point is optional though.. depending on
the design we could ellect to implement this only for shared storage options.
