We are replacing RocksDB with SurrealKV 1.0
Author: Tobie Morgan Hitchcock SurrealKV 1.0 is a new open source persistent storage engine for SurrealDB, written in Rust and released under Apache 2.0 on 13 October 2026. With synchronous durability, it reads 7.95× faster than RocksDB and 73.7× faster than SlateDB, and it will be the only persistent storage engine in SurrealDB 4. Why replace RocksDB? RocksDB is a very good engine, and SurrealDB…
SurrealKV 1.0, an open-source persistent storage engine for SurrealDB, has been released under Apache 2.0. This new engine is written in Rust and promises to be 7.95× faster than RocksDB and 73.7× faster than SlateDB when using synchronous durability. With its design decisions, SurrealKV removes shared work and waiting from the hot path, resulting in faster point reads, updates, and deletes.
It also includes features such as versioned trees, encryption at rest, and differential testing against an in-memory reference model. The benchmark results demonstrate SurrealKV's superior performance in various operations compared to RocksDB and SlateDB.
