Since 2025, 6 different Hacker News readers have linked it 43 times, most often “TidesDB: A fast key/value store for modern hardware”. It is still writing: the last post was on 2026-10-09, and you can follow it by feed.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers link TidesDB's documentation on how the storage engine works. One commenter called the internals document pretty great, saying it goes wide and deep, and saved it for later reading.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
TidesDB is a fast, embeddable LSM-tree storage engine in C — write & space efficient, ACID, faster than RocksDB, with FFI bindings for 9 languages. TideSQL brings it to MariaDB & MySQL.

What Hacker News says?
Indeed! Postgres vacuum can be troublesome on lots of write and delete heavy workloads and no way to just set a table to another engine. TidesDB is highly efficient on amplification rather that be write, read, or space for an LSM based engine. Reads are also pretty great with our LSMB+tree hybrid architecture; You can read about TPC-C analysis against InnoDB in MariaDB (larger than memory) and see TidesDB keeping up…

HN discussionHey hackernews! I'd like to share a project I've been working on for almost a year now. It's an open-source storage engine similar to that of LevelDB/RocksDB but written entirely in C. The storage engine is called TidesDB. TidesDB is an open-source storage engine similar to LevelDB/RocksDB but written entirely in C. It's designed as a fast, transactional key-value storage engine built on a log-structured merge-tree…

HN discussionHey! I'm Alex the creator of TidesDB. I'd like to share the latest major as it's a huge milestone in the development of the open-source project. In recent benchmarks for TidesDB 6 against RocksDB 10.7.5, TidesDB is pulling ahead across most if not all workloads in efficiency and speed. I've written about the design, the benchmarks are available and more. I'd love to hear your thoughts! Website has documentation, des…

HN discussionThe internals document looks pretty great too. It actually talks of internals and goes pretty wide and deep. Saved for reading later once the coffee kicks in! https://tidesdb.com/getting-started/how-does-tidesdb-work/

HN discussionHello hn, I’m Alex the creator of TidesDB and over the past few months I’ve been working on putting TidesDB to work inside MariaDB through a plugin which the project is labeled TideSQL. The project has grown quite a lot where I’d like to share it. The plugin allows for MariaDB to optimize writes; not leave resources on the table and optionally scale infinitely. In tpc-c benchmarks the plugin shows rather great numbe…
