What it is

sled is a pure-Rust embedded ACID transactional database with an API similar to BTreeMap, optimized for flash storage and concurrent access. It provides zero-copy reads, atomic compare-and-swap operations, serializable transactions across multiple key-spaces, and generates 75-125 million unique IDs per second via its crash-safe ID generator. The core problem it solves: applications needing a performant, lock-free in-process database without external dependencies or expensive serialization costs. Single-crate Rust project: src/ contains core engine code organized by logical concerns (src/db.rs for the database entry point, src/tree.rs for key-value operations, src/leaf.rs for storage nodes,…

Start here

Read these in order:

• tests/common/mod.rs — Foundation: doesn't import anything internally and is imported by 6 other files. Read first to learn the vocabulary.
• src/object_location_mapper.rs — Foundation: imported by 2, no internal dependencies of its own.
• tests/crash_tests/mod.rs — Built on the foundation; imported by 1 downstream file.
• src/heap.rs — Built on the foundation; imported by 1 downstream file.
• src/lib.rs — Layer 2 — application-level code that wires the lower layers together.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository and verify the Cargo manifest before building: git clone https://github.com/spacejam/sled.git && cd sled. To build and test the library, run cargo build --release and cargo test (Cargo.toml co…

Daily commands:

This is a library crate, not a standalone application. To use it in a project: add sled = "1.0.0-alpha.124" to your Cargo.toml. To run example code: cargo run --example bench or cargo run --example bench_large (re…

Key cautions & unknowns

• Slowing — last commit 5mo ago
• Small team — 3 contributors active in recent commits
• Single-maintainer risk — top contributor 98% of recent commits
• README is stale: The README explicitly warns it is 'out of sync with the main branch which contains a large in-progress rewrite'—do not treat README examples or feature descriptions as ground truth without…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
