Struct DynamicConfig 

pub struct DynamicConfig {
    pub heartbeat_interval_ms: u64,
    pub compaction_threshold: usize,
}

The subset of NodeConfig that can be hot-reloaded at runtime.

Store this in an Arc<parking_lot::RwLock<DynamicConfig>> inside the cluster node. When the node receives a SIGHUP or an admin RPC requesting a config reload, parse a new NodeConfig and replace the inner value:

*dynamic_config.write() = new_node_config.dynamic();

The Raft event loop reads from Arc<RwLock<DynamicConfig>> for the heartbeat interval, so changes take effect on the next tick without restarting the node.

Fields

heartbeat_interval_ms: u64

Raft heartbeat interval in milliseconds.

compaction_threshold: usize

Log compaction threshold (entries before snapshot).
