Struct kvdb_rocksdb::CompactionProfile

pub struct CompactionProfile {
    pub initial_file_size: u64,
    pub block_size: usize,
}

Compaction profile for the database settings Note, that changing these parameters may trigger the compaction process of RocksDB on startup. https://github.com/facebook/rocksdb/wiki/Leveled-Compaction#level_compaction_dynamic_level_bytes-is-true

Fields

initial_file_size: u64

L0-L1 target file size The minimum size should be calculated in accordance with the number of levels and the expected size of the database.

block_size: usize

block size

Implementations

impl CompactionProfile

pub fn auto<P: AsRef<Path>>(db_path: P) -> CompactionProfile

Attempt to determine the best profile automatically, only Linux for now.

pub fn ssd() -> CompactionProfile

Default profile suitable for SSD storage

pub fn hdd() -> CompactionProfile

Slow HDD compaction profile

Trait Implementations

impl Clone for CompactionProfile

fn clone(&self) -> CompactionProfile

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompactionProfile

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

Formats the value using the given formatter.

impl Default for CompactionProfile

fn default() -> CompactionProfile

Default profile suitable for most storage

impl PartialEq<CompactionProfile> for CompactionProfile

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

This method tests for self and other values to be equal, and is used by ==.

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

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