Propomos uma arquitetura Edge-write que realiza propagação de atualização antecipada para solicitações de atualização para o servidor secundário correspondente, enquanto propaga preguiçosamente atualizações de outros servidores secundários. Nossa arquitetura resolve problemas de consistência causados pelo desacoplamento de leitura/atualização no sistema convencional baseado em propagação de atualização lenta. Ele também melhora a escalabilidade geral, aliviando o gargalo de desempenho no servidor primário em compensação pelo tempo de resposta aumentado, mas limitado. Esse gerenciamento de consistência relaxado permite que uma solicitação de leitura escolha se deseja ler os dados replicados imediatamente ou atualizá-los. Usamos a idade de uma cópia de dados local como fator de atualização para que um servidor secundário possa tomar uma decisão sobre o controle de atualização de forma independente. Como resultado, nossa arquitetura de gravação de borda controlada pela atualização se beneficia ao ajustar uma compensação entre o tempo de resposta e a exatidão dos dados.

Abstract: We propose an Edge-write architecture which performs eager update propagation for update requests for the corresponding secondary server, whereas it lazily propagates updates from other secondary servers. Our architecture resolves consistency problems caused by read/update decoupling in the conventional lazy update propagation-based system. It also improves overall scalability by alleviating the performance bottleneck at the primary server in compensation for increased but bounded response time. Such relaxed consistency management enables a read request to choose whether to read the replicated data immediately or to refresh it. We use the age of a local data copy as the freshness factor so that a secondary server can make a decision for freshness control independently. As a result, our freshness-controlled edge-write architecture benefits by adjusting a tradeoff between the response time and the correctness of data.

AB - We propose an Edge-write architecture which performs eager update propagation for update requests for the corresponding secondary server, whereas it lazily propagates updates from other secondary servers. Our architecture resolves consistency problems caused by read/update decoupling in the conventional lazy update propagation-based system. It also improves overall scalability by alleviating the performance bottleneck at the primary server in compensation for increased but bounded response time. Such relaxed consistency management enables a read request to choose whether to read the replicated data immediately or to refresh it. We use the age of a local data copy as the freshness factor so that a secondary server can make a decision for freshness control independently. As a result, our freshness-controlled edge-write architecture benefits by adjusting a tradeoff between the response time and the correctness of data.
