Field Detail

MAX_CONFIRMATIONS

public static final int MAX_CONFIRMATIONS

Each message container keeps track of the messages that still need to be 'confirmed', i.e. referenced by a subsequent message. All subsequent success responses from the container will reference the unconfirmed messages. When the referencing message is confirmed by the communication partner, the referenced message is no longer regarded as unconfirmed. However, network latency and server load can lead to situations with many 'in-flight' messages. All in-flight messages are unconfirmed, so each message would reference a growing number of other messages, congesting the system even more. To alleviate the situation, the system keeps track of the number of times an unconfirmed message has been referenced, and this number is bounded by N=UNCONFIRMED_QUEUE_SIZE, which means that every unconfirmed message is referenced at most N times by a subsequent message. This may lead to messages ending up unconfirmed.
