Alternative approach: Let a cluster node be initialized, which is an
|
||||||
|
overlay over a repository which shares all of its configuration
|
||||||
|
except for its uuid. Every change to the location log of a cluster
|
||||||
|
node is immediately propigated to every repository that has a connection
|
||||||
|
to it. It is also propigated to the underlaying repository. This lets
|
||||||
|
more than one cluster node be initialized for the same repository, for

|
when it is in multiple clusters or behind multiple gateways in the same
|

|
cluster.
