Method Detail

droppedFromTopic

void droppedFromTopic(int topicId,
                    String topicName)

signaled if this service could not keep up with send rate and requested retransmission of a packet which is already removed from the senders history. This might also happen to senders if they could not process incoming call results fast enough or there are network issues/congestion Reasons are: 1) history buffer of sender is too small 2) network congestions/overload 3) (most frequent) receiver is slow or has long GC pauses after this message, no further messages will be received until reconnects.

senderDied

void senderDied(int topicId,
              String topicName,
              String sender)

called if no heartbeats on topic are received from a sender. This happens if sender is down or has massive GC pauses (larger 30000). This message can be pretty late (30 seconds). Use FCMembershipService in order to get near time notifications on new/leaving cluster members on a topic.

Parameters:

sender -

senderBootstrapped

void senderBootstrapped(int topic,
                      String topicName,
                      String newSender,
                      long seqNo)

called if a new sender joined this topic
