1//! # Delta: Distributed Coordination for LaminarDB
2//!
3//! This module implements multi-node distribution for LaminarDB, extending
4//! the single-process engine with gossip discovery, Raft metadata consensus,
5//! epoch-fenced partition ownership, distributed checkpointing, and gRPC
6//! inter-node RPC.
7//!
8//! ## Architecture

28//!
29//! - `discovery`: Node discovery (static seeds, gossip, Kafka groups)
30//! - `coordination`: Raft-based metadata consensus
31//! - `partition`: Epoch-fenced partition ownership and migration
32//! - `checkpoint`: Distributed checkpoint coordination
33//! - `rpc`: gRPC services for inter-node communication
