You start the first broker without the join option, then subsequent
members are started with the join option giving the address of an
existing cluster member (e.g. the first one started).
- is there any way to configure a cluster using the broker config. I had
initially imagined that you'd be able to do that but couldn't spot a route
in that way ?
You can use a config file for each broker, but not a global file to
startup a set of clustered brokers. The join address can't as yet be
specified in the config either I don't think.
- how do you go about running up more than one cluster on the same host
? (I
had guessed that you'd specify an identifier for the cluster but don't
think
that's correct)
When you start a cluster broker it either forms a new cluster or joins
the cluster referred to be the argument to the join option.
- is there anyway to default failover behaviour in a cluster such that
clients don't have to specify the string of hosts for failover at
connection
time, rather the cluster leader can manage failover from brokers that it
knows about ?
Unfortunately there is not at present.
