Redirect file data according to routing strategy
When pupper master is terminated, it should terminate all operators
Rerouting
Semantics' : At most-once
UDP Protocol (do some research)
Logging (of events) Operations
Quando criar aa replica, passar o endereço do puppet master à replica, para permitir fazer notify

Coordenar diferentes replicas
- quanto tempo é que cada uma mantém o buffer
- se um evento já foi partilhado
- ordem dos eventos
Objetivo: Maximizar replicação evitando reprocessmento de muitos eventos no caso de haver falhas nos nós...
Criar método de reconfiguração automática
Após falha de uma réplica. O grupo de réplicas deverá assegurar que é eleita uma para substituir essa.
[Necessário manter o desempenho deterministico/previsivel apesar de a replica ter falhado]
In case of failures, the system should reconfigure automatically, without disrupting the processing of the stream of tuples. For instance, if a downstream operator crashes, the upstream operato should automatically reconfigure its routing strategy so that he propagates its results only to available replicas of the downstream operator, and no tuples should be lost
Operações Crash, Freeze, Start Unfreeze....
