On the Synchronization Bottleneck of OpenStack Swift-Like Cloud Storage Systems

As one type of the most popular cloud storage services, OpenStack Swift and its follow-up systems replicate each object across multiple storage nodes and leverage null object sync protocols null to achieve high reliability and null eventual consistency . The performance of object sync protocols heavily relies on two key parameters: null null rnull null null null null null (number of replicas for each object) and null null nnull null null...
