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
