Struct PartitionState

pub struct PartitionState {
    pub partition: PartitionKey,
    pub available_bytes: u64,
    pub nodes: Vec<NodeDiskUsage>,
}

Expand description

State of one partition that hosts node data: how much space is free and which running nodes live on it (with their measured sizes).

Fields§

§partition: PartitionKey§available_bytes: u64

Free bytes available on the partition.

§nodes: Vec<NodeDiskUsage>

Running nodes whose data directory lives on this partition.

Implementations§

Source §

impl PartitionState

Source

pub fn eviction_candidate(&self) -> Option<&NodeDiskUsage>

The node that should be evicted first to reclaim space on this partition.

Selection rule: the smallest data directory wins, because evicting a node forces the network to re-replicate everything it held — so we minimise that cascade by dropping the node that holds the least. Ties are broken by preferring the newest node (highest id, least established in the network). Returns None if the partition hosts no nodes.
