SlateDB is an embedded key-value storage engine implemented in Rust as a log-structured merge-tree (LSM) that persists all data to object storage like S3, GCS, and Azure Blob instead of local disks. It offers single-writer/multiple-reader semantics, snapshot isolation, transactions, read caching, and zero-copy clones, with official bindings for Go, Java, Node.js, and Python.
Use cases
- build a key-value database with bottomless storage on S3
- replace RocksDB where local disks are undesirable
- store application state durably in object storage without running a database server
- scale read traffic with multiple readers against one shared dataset
- create zero-copy database clones or forks from checkpoints
- tune write durability versus API cost for cloud-native workloads
When to choose
- you want an embedded LSM engine with no local disk or replication protocol
- you need the durability and economics of S3-class object storage
- you want single-writer with multiple read replicas backed by a shared object store
- you need snapshot isolation, transactions, or cheap zero-copy clones
When to avoid
- you need low-latency writes; object store PUT latency (50-100ms on standard tiers) dominates
- your workload is write-heavy and object store API costs or rate limits would be prohibitive
- you need multi-writer concurrency or a full SQL database
- you need a mature battle-tested engine like RocksDB for latency-critical local storage
