Struct KvSeparationOptions

pub struct KvSeparationOptions { /* private fields */ }

Configuration options for key-value-separated partitions.

Implementations

impl KvSeparationOptions

pub fn file_target_size(self, bytes: u64) -> Self

Sets the target size of blob files.

Smaller blob files allow more granular garbage collection which allows lower space amp for lower write I/O cost.

Larger blob files decrease the number of files on disk and thus maintenance overhead.

Defaults to 128 MiB.

pub fn separation_threshold(self, bytes: u32) -> Self

Sets the key-value separation threshold in bytes.

Smaller value will reduce compaction overhead and thus write amplification, at the cost of lower read performance.

Defaults to 1 KiB.

Trait Implementations

impl Clone for KvSeparationOptions

fn clone(&self) -> KvSeparationOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KvSeparationOptions

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

Formats the value using the given formatter.

impl Decode for KvSeparationOptions

fn decode_from<R: Read>(reader: &mut R) -> Result<Self, DecodeError>

where Self: Sized,

Deserializes from reader.

impl Default for KvSeparationOptions

fn default() -> Self

Returns the “default value” for a type.

impl Encode for KvSeparationOptions

fn encode_into<W: Write>(&self, writer: &mut W) -> Result<(), EncodeError>

Serializes into writer.

fn encode_into_vec(&self) -> Vec<u8>

Serializes into vector.

impl PartialEq for KvSeparationOptions

fn eq(&self, other: &KvSeparationOptions) -> 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.
