Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Anyone using io_uring?
Basically io_uring grew a lot, the latest API offers incredible tools but there are very few examples in any language (xnvme and fio), and in particular I'm struggling to understand how to do it in Rust: where should unsafe code stop? should I simply expose the io_uring api as unsafe, or should I do more work in C and present the ring when ready to rust?

libnvme VS xNVMe - a user suggested alternative
2 projects | 4 Mar 2022
The foundation of xNVMe is libxnvme, a user space library for working with NVMe devices. It provides a C API for memory management, that is, for allocating physical / DMA transferable memory when needed. An NVMe command interface allowing you to submit and complete NVMe commands in a synchronous as well as an asynchronous manner. Similar to libnvme, however, with a focus on I/O performance and portability. Thus, xNVMe and the libxnvme library works not just on Linux, but also on FreeBSD, Windows, and MacOS.

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?
libnvme - C Library for NVM Express on Linux
solid_cache - A database-backed ActiveSupport::Cache::Store
VkFFT - Vulkan/CUDA/HIP/OpenCL/Level Zero/Metal Fast Fourier Transform library
uNVMe - KV and LBA SSD userspace NVMe driver
fio - Flexible I/O Tester
ssd-nvme-database - Columnar database on SSD NVMe
FEMU - FEMU: Accurate, Scalable and Extensible NVMe SSD Emulator (FAST'18). Please checkout https://github.com/vtess/FEMU for latest developments.
KVSSD - KV SSD host software including APIs and drivers
openSeaChest - Cross platform utilities useful for performing various operations on SATA, SAS, NVMe, and USB storage devices.
kivi - Dynamo-inspired distributed leader-less key-value database that has no unique features and no apparent reason to exist
yottaStore - A datastore aiming at linear scalability up to the yottabyte range. Inspired by dynamo and cassandra.
