System scaling becomes essential and indispensable for distributed storage systems due to the explosive growth of data volume. Considering that fault-protection is a necessity in large-scale distributed storage systems, and Cauchy Reed-Solomon (CRS) …
Although the travel time is the most important information in road networks, many spatial queries, e.g., $k$ -nearest-neighbor ( $k$ -NN) and range queries, for location-based services (LBS) are only based on the network distance. This is because it …
Distributed storage systems provide large-scale data storage services, yet they are confronted with frequent node failures. To ensure data availability, a storage system often introduces data redundancy via replication or erasure coding. As erasure …
Modern distributed storage systems often deploy deduplication to remove content-level redundancy and hence improve storage efficiency. However, deduplication inevitably leads to unbalanced data placement across storage nodes, thereby degrading read …
