  • Ask HN: Why are there no open source NVMe-native key value stores in 2023?
    12 projects | news.ycombinator.com | 16 Oct 2023
    I don't remember exactly why I have any of them saved, but these are some experimental data stores that seems to be fitting what you're looking for somewhat:

    - https://github.com/DataManagementLab/ScaleStore - "A Fast and Cost-Efficient Storage Engine using DRAM, NVMe, and RDMA"

    - https://github.com/unum-cloud/udisk - "The fastest ACID-transactional persisted Key-Value store designed for NVMe block-devices with GPU-acceleration and SPDK to bypass the Linux kernel."

    - https://github.com/capsuleman/ssd-nvme-database - "Columnar database on SSD NVMe"

What are some alternatives?

When comparing uNVMe and udisk you can also consider the following projects:

solid_cache - A database-backed ActiveSupport::Cache::Store

KVRocks - RocksDB compatible key value store and MyRocks compatible storage engine designed for KV SSD

ssd-nvme-database - Columnar database on SSD NVMe

KVSSD - KV SSD host software including APIs and drivers

yottaStore - A datastore aiming at linear scalability up to the yottabyte range. Inspired by dynamo and cassandra.

ScaleStore - This is the source code for our (Tobias Ziegler, Carsten Binnig and Viktor Leis) published paper at SIGMOD’22: ScaleStore: A Fast and Cost-Efficient Storage Engine using DRAM, NVMe, and RDMA.

kivi - Dynamo-inspired distributed leader-less key-value database that has no unique features and no apparent reason to exist
