Struct ClusterSection 

pub struct ClusterSection {
    pub enabled: bool,
    pub port_base: u16,
    pub node_id: String,
    pub elect_port_base: u16,
    pub peers: Vec<PeerEntry>,
    pub scopes: Vec<ScopeEntry>,
}

[cluster] section — single-node cluster mode: keys route by Redis-cluster slot (CRC16 {hashtag} & 16383) and every shard i gets a second, deterministic listener at port_base + i that answers wrong-shard keys with -MOVED, so stock cluster-aware clients (redis-benchmark --cluster, redis-cli -c) can address shards directly. The main SO_REUSEPORT port keeps full forward-anywhere behaviour for non-cluster clients. Not hot-settable: the routing scheme is a startup property of the data dir (shards.meta).

The struct is Clone but not Copy (since peers and scopes hold owned vectors). Most call sites just clone the per-tick Config snapshot via Arc<Config>, so this is invisible in the hot path.

Fields

enabled: bool

Enable cluster mode. Default false (zero change).

port_base: u16

First cluster port (shard i listens at port_base + i). 0 (default) = server.port + 1.

node_id: String

This node’s stable id for the quorum election (≤ 32 B ASCII; unique across the cluster). Default empty — kevy-elect is dormant unless both node_id and peers are set, so existing configs need no edit.

elect_port_base: u16

First election-control listener port; shard i binds at elect_port_base + i. Default 0 → server.port + 200 (locked by the resolved_elect_port_base unit test).

peers: Vec<PeerEntry>

Operator-declared peer list for kevy-elect. Empty when failover is not configured. Each entry is one cluster node (including potentially this node — kevy-elect filters self by matching node_id).

scopes: Vec<ScopeEntry>

Scope declarations: each entry pins a key prefix to a writer node (and optional fallback). Empty when scope-based multi-writer is off. Same flat-string TOML shape as peers — scopes = "prefix=writer[|fallback],...".
