Неожиданный рост интервала между сплетнями и увеличением размера сообщений в распределенных данных Akka

2 голосов
/ 09 апреля 2019

Я использую распределенные данные Akka для репликации данных заказа между тремя узлами.В настоящее время я использую только типы CRetT GSet и LWWRegister.Но вскоре после того, как сообщение отправлено репликатору, интервал сплетен увеличивается, и репликатор регистрирует ошибку сериализации, отмечая, что максимально допустимый размер сообщения был превышен.Та же самая ошибка может быть воспроизведена даже с меньшим значением сообщения, таким как символ.Примерно через 10 минут работы кучи Java не хватает памяти.

Я следовал документации Akka, опубликованной здесь , чтобы внедрить систему.

Я искал решение для этого в течение нескольких дней и уже пытался изменить application.conf, чтобы разрешить больший размер фрейма, увеличить интервал сплетен ddata и изолировать часть приложения для репликации данных и запустить его.Я попробовал следующие методы, и они не дали мне правильного решения. 1 , 2 , 3

Вот часть моего application.conf, связанная с удаленным Akka и данными Akka 

remote.artery {
    enabled = on
    transport = tcp
    canonical.port = 5053
    canonical.hostname = 127.0.0.1
    advanced {
            maximum-frame-size = 256KiB
            buffer-pool-size = 128
            maximum-large-frame-size = 4MiB
            large-buffer-pool-size = 32
    }
.....

akka.cluster.distributed-data {
  name = ddataReplicator
  role = "AthenaLB_1"
  gossip-interval = 2 s
  notify-subscribers-interval = 500 ms
  max-delta-elements = 1000
  use-dispatcher = ""
  pruning-interval = 120 s
  max-pruning-dissemination = 300 s
  pruning-marker-time-to-live = 6 h
  serializer-cache-time-to-live = 60 s

  # Settings for delta-CRDT
  delta-crdt {
    enabled = on
    max-delta-size = 200
  }

  durable {
    keys = []
    pruning-marker-time-to-live = 10 d
    store-actor-class = akka.cluster.ddata.LmdbDurableStore
    use-dispatcher = akka.cluster.distributed-data.durable.pinned-store
    pinned-store {
      executor = thread-pool-executor
      type = PinnedDispatcher
    }

    lmdb { 
      dir = "ddata"
      map-size = 100 MiB
      write-behind-interval = off
    }
  }

Вот методы, которые я использовал для репликации состояния между узлами.Обратите внимание, что я опустил ненужные части кода. 

private final ActorRef replicator = DistributedData.get(getContext().getSystem()).replicator();
private final SelfUniqueAddress node = DistributedData.get(getContext().getSystem()).selfUniqueAddress();
private static final Replicator.ReadConsistency readMajority = new Replicator.ReadMajority(Duration.ofSeconds(30));
private final Replicator.WriteConsistency writeMajority = new Replicator.WriteMajority(Duration.ofSeconds(30));


private void replicateState(ExchangeSupervisorProtos.SavedExchangeList recovery) {
    LOGGER.info("Sending replication message: {}", recovery.toString());
    Replicator.Update<LWWRegister<ExchangeSupervisorProtos.SavedExchangeList>> update = new Replicator.Update<>(
                        exchangeSupervisorRecoveryKey,
                        LWWRegister.create(node, recovery),
                        writeMajority,
                        curr -> updateExchangeSupervisorRecovery(curr, recovery));
        replicator.tell(update, self());
}

private LWWRegister<ExchangeSupervisorProtos.SavedExchangeList>   updateExchangeSupervisorRecovery(LWWRegister<ExchangeSupervisorProtos.SavedExchangeList> data,
ExchangeSupervisorProtos.SavedExchangeList recovery) {

return data.withValue(DistributedData.get(node, recovery,LWWRegister.defaultClock());
}

private void replicateState(ExchangeRecovery recovery) {
        LOGGER.info("Sending replication message: {}", recovery.toString());
        Replicator.Update<GSet<ExchangeRecovery>> update =
                new Replicator.Update<>(
                        exchangeRecoveryKey,
                        GSet.create(),
                        writeMajority,
                        curr -> updateExchangeRecovery(curr, recovery));
        replicator.tell(update, self());
    }

private GSet<ExchangeRecovery>
    updateExchangeRecovery(GSet<ExchangeRecovery> data,
                           ExchangeRecovery recovery) {
    return data.add(recovery);
}

Вот часть журналов узла.

Возможно, мой подход неверен, так как я толькоработаю с Akka ddata уже две недели.Если кто-то знает, почему это происходит, возможная причина или возможное решение, пожалуйста, помогите мне.Спасибо.
