The OMRS Cluster Registry Store stores information about the repositories registered in the open metadata repository cluster.
Figure 1: Cluster registry stores in an open metadata repository cluster | Each server in the open metadata repository cluster runs an OMRS Cluster Registry to manage its registration with the cluster and maintain the contents of its local cluster registry store. |
Figure 2: logical structure of the cluster registry store | Each member in the open metadata repository cluster is represented in the cluster registry store with a member registration record. This has 3 values in it:
Inside the cluster registry store is a record of the local server's registration and a list of registration record for each remote repository that it knows about. |
The OMRS Cluster Registry store is implemented as an OCF Connector so the implementation is configurable. The initial implementation is a file based store that uses JSON.
