Implementations

impl<EK, R> SnapContext<EK, R> where
    EK: KvEngine,
    R: CasualRouter<EK>, [src][−]

fn generate_snap(
    &self,
    region_id: u64,
    last_applied_index_term: u64,
    last_applied_state: RaftApplyState,
    kv_snap: EK::Snapshot,
    notifier: SyncSender<RaftSnapshot>,
    for_balance: bool
) -> Result<(), Error>[src][−]

Generates the snapshot of the Region.

fn handle_gen(
    &self,
    region_id: u64,
    last_applied_index_term: u64,
    last_applied_state: RaftApplyState,
    kv_snap: EK::Snapshot,
    canceled: Arc<AtomicBool>,
    notifier: SyncSender<RaftSnapshot>,
    for_balance: bool
)[src][−]

Handles the task of generating snapshot of the Region. It calls generate_snap to do the actual work.

fn apply_snap(
    &mut self,
    region_id: u64,
    abort: Arc<AtomicUsize>
) -> Result<(), Error>[src][−]

Applies snapshot data of the Region.

fn handle_apply(&mut self, region_id: u64, status: Arc<AtomicUsize>)[src][−]

Tries to apply the snapshot of the specified Region. It calls apply_snap to do the actual work.

fn cleanup_range(&self, ranges: &[Range<'_>]) -> Result<(), Error>[src][−]

Cleans up the data within the range.

fn cleanup_overlap_ranges(
    &mut self,
    start_key: &[u8],
    end_key: &[u8]
) -> Result<(), Error>[src][−]

Gets the overlapping ranges and cleans them up.

fn insert_pending_delete_range(
    &mut self,
    region_id: u64,
    start_key: &[u8],
    end_key: &[u8]
)[src][−]

Inserts a new pending range, and it will be cleaned up with some delay.

fn clean_stale_ranges(&mut self)[src][−]

Cleans up stale ranges.

fn ingest_maybe_stall(&self) -> bool[src][−]

Checks the number of files at level 0 to avoid write stall after ingesting sst. Returns true if the ingestion causes write stall.

fn delete_all_in_range(&self, ranges: &[Range<'_>]) -> Result<(), Error>[src]
