HashKV-4.6× throughput than key-value separation design [pdf]
HashKV-4.6× throughput than key-value separation design [pdf] launched on August 5, 2018 with 10 votes, #941 of 2,619 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 8 years on.
In plain words
HashKV is a key-value storage system designed to improve performance over traditional key-value separation approaches. It achieves 4.6 times higher throughput than comparable designs. The system is aimed at developers and engineers working with data storage solutions who need improved efficiency in handling large-scale key-value operations. HashKV was launched in 2018 and is documented in a research paper available through USENIX.

Minikv – Distributed key-value and object store in Rust (Raft, S3 API)Feb 2026 · github.com · ▲71Hi HN, I'm Emilie, I have a literature background (which explains the well-written documentation!) and I've been learning Rust and distributed systems by building minikv over the past few months. It recently got featured in Programmez! magazine: https://www.programmez.com/actualites/minikv-un-key-value-st... minikv is an open-source, distributed storage engine built for learning, experimentation, and self-hosted setups. It combines a strongly-consistent key-value database (Raft), S3-compatible object storage, and basic multi-tenancy. Features/highlights: - Raft…
Tinykv – Minimal file-backed key-value store for Rust2025 · crates.io · ▲24I built tinykv because I kept reaching for simple persistent storage in Rust projects but found existing solutions either too complex (sled) or unmaintained (pickledb). tinykv focuses on simplicity: JSON-based, serde-powered, with optional TTL. Perfect for CLI tools, game saves, config storage. Would appreciate any feedback from the HN community!
A hash array-mapped trie implementation in C2023 · github.com · ▲171Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

- ESEloqKV – Scalable distributed ACID key-value database with Redis API2024 · eloqdata.com · ▲44
We're thrilled to unveil EloqKV, a lightning-fast distributed key-value store with a Redis-compatible API. Built on a new database architecture called the Data Substrate, EloqKV brings significant innovations to database design. Here’s the unique features that makes it stand out: - Flexible Deployment: Run it as a single-node in-memory KV cache, a larger-than-memory database or scale to a highly available, distributed transactional database with ease. - High Performance: Achieves performance levels comparable to top in-memory databases like Redis and DragonflyDB, while significantly…

Retool▲640Hi all, founder @ Retool here. We initially launched Retool on HN five years ago: https://news.ycombinator.com/item?id=14515494. The feedback was extraordinarily helpful then (e.g. we launched source control, on-prem, etc. based on HN comments), and we’re grateful for all of it. Today, we’re excited to get HN’s thoughts on one of our new products: Retool Mobile. It lets you build and deploy mobile apps in minutes, not days. The idea is there is a large class of line-of-business mobile apps, and the process of getting a simple form + button on a mobile device, in a native app,…
