Struct CompactOptions 

pub struct CompactOptions { /* private fields */ }

Implementations

impl CompactOptions

pub fn set_exclusive_manual_compaction(&mut self, v: bool)

If more than one thread calls manual compaction, only one will actually schedule it while the other threads will simply wait for the scheduled manual compaction to complete. If exclusive_manual_compaction is set to true, the call will disable scheduling of automatic compaction jobs and wait for existing automatic compaction jobs to finish.

pub fn set_bottommost_level_compaction( &mut self, lvl: BottommostLevelCompaction, )

Sets bottommost level compaction.

pub fn set_change_level(&mut self, v: bool)

If true, compacted files will be moved to the minimum level capable of holding the data or given level (specified non-negative target_level).

pub fn set_target_level(&mut self, lvl: c_int)

If change_level is true and target_level have non-negative value, compacted files will be moved to target_level.

pub fn set_full_history_ts_low<S: Into<Vec<u8>>>(&mut self, ts: S)

Set user-defined timestamp low bound, the data with older timestamp than low bound maybe GCed by compaction. Default: nullptr

pub fn set_blob_garbage_collection_age_cutoff(&mut self, v: c_double)

Override CompactRangeOptions::blob_garbage_collection_age_cutoff for a single manual compaction.

If set to < 0 or > 1, RocksDB leaves the blob_garbage_collection_age_cutoff from ColumnFamilyOptions in effect (this is the default, -1). Otherwise, it overrides the user-provided setting for the duration of this compaction. This enables callers to selectively override the age cutoff per compact_range call.

See Options::set_blob_gc_age_cutoff for the CF-level setter that this value overrides.

Trait Implementations

impl Default for CompactOptions

fn default() -> Self

Returns the “default value” for a type.

impl Drop for CompactOptions

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
