Ask HN: Why are there no open source NVMe-native key value stores in 2023?
https://github.com/OpenMPDK/uNVMe/blob/master/doc/uNVMe2.0_S...
I can't find detailed spec sheets detailing which NVMe command sets are supported even for their enterprise drives.

Ask HN: Why are there no open source NVMe-native key value stores in 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?
solid_cache - A database-backed ActiveSupport::Cache::Store
KVSSD - KV SSD host software including APIs and drivers
ssd-nvme-database - Columnar database on SSD NVMe
KVRocks - RocksDB compatible key value store and MyRocks compatible storage engine designed for KV SSD
kvrocks - Apache Kvrocks is a distributed key value NoSQL database that uses RocksDB as storage engine and is compatible with Redis protocol.
xnvme - Portable and high-performance libraries and tools for NVMe devices as well as support for traditional/legacy storage devices/interfaces.
yottaStore - A datastore aiming at linear scalability up to the yottabyte range. Inspired by dynamo and cassandra.
