Struct SplitPolicy 

pub struct SplitPolicy {
    pub max_whole_move_bytes: u64,
    pub hot_traffic_threshold: u64,
}

The thresholds that decide whether a range is small enough to move whole or must be split first.

The two are independent and either trips a split: a range can be small on disk yet a traffic hotspot, or quiet yet too large to copy and cut over as one unit. Splitting in either case lets the move shed only a subrange instead of relocating the whole load at once.

Fields

max_whole_move_bytes: u64

A range strictly above this many bytes is “large” — too big to copy and cut over whole, so it is split and only a subrange moves.

hot_traffic_threshold: u64

A range serving at or above this much read+write traffic in the observation window is “hot” — split so the move relocates only part of the traffic.

Trait Implementations

impl Clone for SplitPolicy

fn clone(&self) -> SplitPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SplitPolicy

impl Debug for SplitPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for SplitPolicy

fn default() -> SplitPolicy

Returns the “default value” for a type.

impl Eq for SplitPolicy

impl PartialEq for SplitPolicy

fn eq(&self, other: &SplitPolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
