# KiviDB

7 Hacker News commenters recommended KiviDB and 2 criticized it, November 2025 to November 2026. It was recommended in 1 of 13 months.

**Verdict:** Recommended as a faster Redis-compatible in-memory database with strong benchmark numbers. Critics say its write pauses grow with key count.

## Why people recommend it

- Strong benchmark results (3 comments): "at 100 B GET and pipeline 16, valkey is at 1.61M against 19.71M ops/s for kividb" ([source](https://news.ycombinator.com/item?id=50154736)) "The benchmark numbers are impressive." ([source](https://news.ycombinator.com/item?id=50155776)) "the p99 is sub millisecond" ([source](https://news.ycombinator.com/item?id=50155507))
- Scales across all CPU cores (2 comments): "With 1.1 we are on par when compared only based on command execution, however it terms of IO kividb performs better." ([source](https://news.ycombinator.com/item?id=50165501)) "It is mostly because kividb can utilize all the cores you can allow on a machine" ([source](https://news.ycombinator.com/item?id=50156726))

## What people warn about

- Benchmark fairness questioned (2 comments): "this benchmark was run on an earlier version of kividb, which still had several memory management issues" ([source](https://news.ycombinator.com/item?id=50155322)) "Therefore, the test would be biased as the thread pool would become completely starved." ([source](https://news.ycombinator.com/item?id=50156303))
