Erasure codes are an integral part of many distributed storage systems aimed at Big Data, since they provide high fault-tolerance for low overheads. However, traditional erasure codes are inefficient on replenishing lost data (vital for long term resilience) and on reading stored data in degraded environments (when nodes might be unavailable). Consequently, novel codes optimized to cope with distributed storage system nuances are vigorously being researched. In this paper, we take an… CONTINUE READING
