Struct SstFileManager 

pub struct SstFileManager(/* private fields */);

Implementations

impl SstFileManager

pub fn new() -> Self

Creates a new SstFileManager using the default Env.

SstFileManager tracks and controls total SST file space usage, enabling applications to cap disk utilization and throttle deletions. see docs for more details.

pub fn set_max_allowed_space_usage(&self, bytes: u64)

Sets the maximum allowed total SST file size in bytes.

pub fn set_compaction_buffer_size(&self, bytes: u64)

Sets the compaction buffer size in bytes used by the manager for space accounting.

pub fn is_max_allowed_space_reached(&self) -> bool

Returns true if the total SST file size has reached or exceeded the configured limit.

pub fn is_max_allowed_space_reached_including_compactions(&self) -> bool

Returns true if the space limit is reached, including compaction output under accounting.

pub fn get_total_size(&self) -> u64

Returns the total size of SST files tracked by this manager in bytes.

pub fn get_delete_rate_bytes_per_second(&self) -> i64

Returns the configured file deletion rate in bytes per second. Negative means unlimited.

pub fn set_delete_rate_bytes_per_second(&self, rate: i64)

Sets the file deletion rate in bytes per second. Use a negative value to disable limiting.

pub fn get_max_trash_db_ratio(&self) -> f64

Returns the maximum trash-to-DB size ratio used for trash space control.

pub fn set_max_trash_db_ratio(&self, ratio: f64)

Sets the maximum trash-to-DB size ratio used for trash space control.

pub fn get_total_trash_size(&self) -> u64

Returns the total trash size tracked by this manager in bytes.
