• BoringDB: A high-performance key-value store built on SQLite

  This article is from 2021.

  They indeed use an SQL database and SQL queries to implement a key-value store. The data is stored in a regular table (CREATE TABLE example (key BLOB PRIMARY KEY, value BLOB NOT NULL). It's very unlikely that this really achieves high-performance, given that the SQLite backend is actually a key-value store and the SQL interpreter runs on top of it as an intermediate layer. To avoid some performance-drawbacks caused by this architecture they added caching.

  They have even considered RocksDB and LMDB, but have rejected them with reasons that I can not relate.

  I have implemented a transactional key-value store myself for my project and information management tools fifteen years ago (before the other mentioned stores became available) based on the aforementioned SQLite backend (see https://github.com/rochus-keller/Udb and https://github.com/rochus-keller/Sdb) which supports both robust integrity and high performance. Doing the same with the full SQLite just adds complexity and lowers performance with no added value.

• I use Org Mode for personal logging/journalling

  I implemented my own NoSql database for Crossline which supports an efficient storage and traversal of outline items (see https://github.com/rochus-keller/Udb). Even if there was a dedicated API in Emacs/Org-mode it's still file based text buffer interpretation and management behind the scenes.

• Ask HN: What is the SQLite of nosql databases?

  SQLite has a backend which is well suited as a key-value store.

  Here is a NoSql database based on the SQLite backend: https://github.com/rochus-keller/Udb.

  I use it in many of my apps, e.g. https://github.com/rochus-keller/CrossLine
