Overview
SlateDB is an open-source embedded key-value database, implemented as an LSM tree, that persists data directly to object storage such as S3, R2 or GCS rather than local disks. It has a Rust core with Go, Java, Node and Python bindings, and offers single-writer, multi-reader deployment, transactional semantics, and zero-copy clones and branches.
