    Compaction plays a crucial role in NoSQL systems to ensure a high overall read throughput. In this work, we formally define compaction as an optimization problem that attempts to minimize disk I/O.We prove this problem to ...

    Distributed systems are typically designed for scale and performance first, which often makes it difficult to add security later without affecting the original properties. This paper proposes the design of the Folklore ...
