Repair pipelining for erasure-coded storage: Algorithms and evaluation

X Li, Z Yang, J Li, R Li, PPC Lee, Q Huang… - ACM Transactions on …, 2021 - dl.acm.org
We propose repair pipelining, a technique that speeds up the repair performance in general
erasure-coded storage. By carefully scheduling the repair of failed data in small-size units …

A reliable storage partition for permissioned blockchain

X Qi, Z Zhang, C **, A Zhou - IEEE Transactions on …, 2020 - ieeexplore.ieee.org
The full-replication data storage mechanism, as commonly utilized in existing blockchains, is
the barrier to the system's scalability, since it retains a copy of entire blockchain at each …
