Finally, we have to specify the cluster event. The purpose is to allow (whitelist) or block (blacklist) specific cluster events. For instance, we want to block the following:
The cluster event that contains a change in the feature named
my-featureThe cluster event that contains a change in the bundle named
my-bundle
So, we have to identify and declare the cluster event. To identify a cluster event, we can use the following:
The event identifier can be used; for instance,
org.apache.karaf.cellar.groupsidentifies the configuration's cluster event (PID).A regular expression (regex) or glob based on the event identifier can be used. Declaring events using the full qualified name can be tedious. The usage of a regex is much faster. For instance,
org.apache.karaf.cellar.*identified all the configuration cluster events containing PIDs.*selects all cluster events.The
nonekeyword is a reserved keyword to not select any cluster event.
The identification depends on...
