Software Support for Non-Volatile Memory (NVM) Programming

David Teksen Aksun

Non-Volatile Memory (NVM) is an emerging type of memory device that provides fast, byte-addressable, and high-capacity durable storage. NVM sits on the memory bus and allows durable data structures designs similar to the in-memory equivalent ones. Expensiv ...

State Machine Replication is More Expensive than Consensus

Rachid Guerraoui, Karolos Antoniadis, Dragos-Adrian Seredinschi

Consensus and State Machine Replication (SMR) are generally considered to be equivalent problems. In certain system models, indeed, the two problems are computationally equivalent: any solution to the former problem leads to a solution to the latter, and v ...

TRIAD: creating synergies between memory, disk and log in log structured key-value stores

Rachid Guerraoui, Willy Zwaenepoel, Diego Didona, Oana Maria Balmau

We present TRIAD, a new persistent key-value (KV) store based on Log-Structured Merge (LSM) trees. TRIAD improves LSM KV throughput by reducing the write amplification arising in the maintenance of the LSM tree structure. Although occurring in the backgrou ...

Online Updates on Data Warehouses via Judicious Use of Solid-State Storage

Anastasia Ailamaki, Radu Ioan Stoica, Manoussos Gavriil Athanassoulis

Data warehouses have been traditionally optimized for read-only query performance, allowing only offline updates at night, essentially trading off data freshness for performance. The need for 24x7 operations in global markets and the rise of online and oth ...
