Tonbo is an embedded database library written in Rust for serverless and edge runtimes, storing data as Parquet files on S3 with coordination via a manifest and fully stateless compute. It is Arrow-native, fully async, supports MVCC transactions, and runs on Tokio, WASM, or edge environments like Cloudflare Workers.
Use cases
- embed a durable state layer in serverless or edge apps without running a database server
- store append-heavy event data directly in S3 and query it with low overhead
- embed an MVCC + Parquet storage engine inside custom data infrastructure
- run structured persistence in WASM or Cloudflare Workers
- query Parquet files on S3 with Arrow RecordBatch zero-copy scans
- build offline-first applications with local embedded storage
When to choose
- you need an embedded, in-process database with no separate database service to manage
- your compute is stateless (serverless/edge) but your data must be durable on object storage
- you want open Parquet files readable by any tool rather than a proprietary format
- you are building in Rust and want an async-first, Arrow-native storage engine
When to avoid
- you need a full client-server SQL database with rich joins and multi-writer coordination
- your workload is write-heavy with frequent updates and deletes rather than append-heavy
- you need strong cross-process or cross-instance transactional guarantees
- you require mature, battle-tested stability for critical production workloads
