Timeout to wait for UNBLOCK after STOP_FLUSH is issued. Default is 2000 msec
Retry timeout after an unsuccessful attempt to quiet the cluster (first flush phase). Default is 3000 msec
Reconciliation phase toggle. Default is true
When set, FLUSH is bypassed, same effect as if FLUSH wasn't in the config at all
Determines whether to collect statistics (and expose them via JMX). Default is true
Enables ergonomics: dynamically find the best values for properties at runtime
Give the protocol a different name if needed so we can have multiple instances of it in the same stack (also change ID)
Fully qualified name of a class implementing ProtocolHook, will be called after creation of the protocol (before init())
Give the protocol a different ID if needed so we can have multiple instances of it in the same stack
logger level (see javadocs)

Name of the site (needs to be defined in the configuration)
Name of the relay configuration
Whether or not this node can become the site master. If false, and we become the coordinator, we won't start the bridge(s)
Maximum number of site masters. Setting this to a value greater than 1 means that we can have multiple site masters. If the value is greater than the number of cluster nodes, everyone in the site will be a site master (and thus join the global cluster
Whether or not we generate our own addresses in which we use can_become_site_master. If this property is false, can_become_site_master is ignored
Whether or not to relay multicast (dest=null) messages
If true, the creation of the relay channel (and the connect()) are done in the background. Async relay creation is recommended, so the view callback won't be blocked
If true, logs a warning if the FORWARD_TO_COORD protocol is not found. This property might get deprecated soon
Fully qualified name of a class implementing SiteMasterPicker
If true, a site master forwards messages received from other sites to randomly chosen members of the local site for load balancing, reducing work for itself
