Corrosion is a Rust-based distributed system that propagates SQLite state across a cluster using gossip (SWIM membership via Foca) and CRDT conflict resolution (CR-SQLite). Each node runs an agent exposing a local HTTP API for SQL reads/writes, query subscriptions, and QUIC-secured peer-to-peer sync.
Use cases
- service discovery across a large global network without a central state store
- replace Consul's central database with eventually consistent distributed state
- read cluster state locally with sub-millisecond latency instead of remote round-trips
- subscribe to SQL query results over HTTP streaming for live config updates
- populate configuration files from distributed state with Rhai templates
- run a multi-writer SQLite database that syncs across many nodes
When to choose
- you need fast, eventually consistent shared state across a large fleet of hosts
- round-trips to a centralized Raft-based store like Consul are too slow for your use case
- you want flexible schemas and SQL queries with local reads on every node
- you need live subscriptions to state changes for config generation
When to avoid
- you need strong/serializable consistency guarantees rather than eventual consistency
- your cluster is small enough that a conventional database or Consul works fine
- you need a general-purpose relational database with full SQLite feature coverage
- you require mature, battle-tested documentation and a large community
