    • getReplicaCount

      public int getReplicaCount()
      Returns the number of replicas on which state for this PN counter will be kept. This number applies in quiescent state, if there are currently membership changes or clusters are merging, the state may be temporarily kept on more replicas.
      Returns:
      the number of replicas for the CRDT state

    • setReplicaCount

      public PNCounterConfig setReplicaCount(int replicaCount)
      Sets the number of replicas on which state for this PN counter will be kept. This number applies in quiescent state, if there are currently membership changes or clusters are merging, the state may be temporarily kept on more replicas.

      The provided replicaCount must be between 1 and 2147483647.

      Parameters:
      replicaCount - the number of replicas for the CRDT state
      Returns:
      the updated PN counter config
      Throws:
      InvalidConfigurationException - if the replicaCount is less than 1
