Fork-based background save

Implementations§

Source §

impl ForkBasedPersistence

Source

pub fn new<P: AsRef<Path>>(data_dir: P) -> Self

Source

pub fn bgsave( &self, collections: &HashMap<String, Arc<Collection>>, ) -> Result<bool>

Start background save (bgsave) - forks a child process

Source

pub fn load_snapshot(&self) -> Result<Option<SnapshotData>>

Load snapshot from disk (on startup) Handles corruption gracefully:

Validates data integrity
Backs up corrupt files
Returns None instead of crashing
Logs detailed warnings

Source

pub fn is_bgsave_in_progress() -> bool

Check if background save is in progress

Source

pub fn last_save_time() -> u64

Get last save time

Source

pub fn save(&self, collections: &HashMap<String, Arc<Collection>>) -> Result<()>

Force save (synchronous, blocks until complete) Uses atomic rename pattern and version markers for data integrity
