The increases in main-memory sizes over the last decade have made pure in-memory
database systems feasible, and in-memory systems offer unprecedented performance …

Modern block-addressable NVMe SSDs provide much higher bandwidth and similar
performance for random and sequential access. Persistent key-value stores (KVs) designed …

Non-volatile memory (NVM) is a new storage technology that combines the performance
and byte addressability of DRAM with the persistence of traditional storage devices like flash …

In-memory databases (IMDBs) store all working data in the main memory, making memory
access the dominant factor in system performance. Moreover, for modern multi-version …

In this paper, we propose ScaleStore, a novel distributed storage engine that exploits DRAM
caching, NVMe storage, and RDMA networking to achieve high performance, cost-efficiency …

The specific characteristics of graph workloads make it hard to design a one-size-fits-all
graph storage system. Systems that support transactional updates use data structures with …

NVMe SSDs based on flash are cheap and offer high throughput. Combining several of
these devices into a single server enables 10 million I/O operations per second or more. Our …

PCIe-attached solid-state drives offer high throughput and large capacity at low cost. Modern
servers can easily host 4 or 8 such SSDs, resulting in an aggregated bandwidth that hitherto …

Many modern key-value stores, such as RocksDB, rely on log-structured merge trees
(LSMs). Originally designed for spinning disks, LSMs optimize for write performance by only …

Most database management systems cache pages from storage in a main memory buffer
pool. To do this, they either rely on a hash table that translates page identifiers into pointers …
