CRDT — Koder Conflict-free Replicated Data Types

• *rea:*Data Platform
• *ath:*data/crdt
• *ind:*Rust library — primitives for multi-cluster replication

Role in the stack

Provides lowlevel CRDT primitives (GCounter, LWWRegister, ORSet, Vector Clock) used by KDB and any Koder service that needs eventual-consistency guarantees across multiple data centers or edge nodes. Designed as a pure library — no server, no network layer. Consumers embed it directly.

Primary couplings

Interfaces

• Rust crate koder-crdt — imported as workspace dependency
• Implements serde::Serialize/Deserialize for Protobuf/JSON interchange via prost
• All types implement Merge trait for commutative, associative, idempotent merges

Status

v0.1.0 — GCounter, LWWRegister, ORSet, Vector Clock implemented. In active use by kdbnext.
