#[repr(C)]pub struct IngestExternalFileOptions { /* fields omitted */ }

IngestExternalFileOptions is used by ingest_external_file()

Implementations

impl IngestExternalFileOptions

pub fn move_files(self, val: bool) -> Self

Can be set to true to move the files instead of copying them.

pub fn snapshot_consistency(self, val: bool) -> Self

If set to false, an ingested file keys could appear in existing snapshots that where created before the file was ingested.

pub fn allow_global_seqno(self, val: bool) -> Self

If set to false, IngestExternalFile() will fail if the file key range overlaps with existing keys or tombstones in the DB.

pub fn allow_blocking_flush(self, val: bool) -> Self

If set to false and the file key range overlaps with the memtable key range (memtable flush required), IngestExternalFile will fail.

pub fn ingest_behind(self, val: bool) -> Self

Set to true if you would like duplicate keys in the file being ingested to be skipped rather than overwriting existing data under that key. Usecase: back-fill of some historical data in the database without over-writing existing newer version of data.

This option could only be used if the DB has been running with allow_ingest_behind=true since the dawn of time. All files will be ingested at the bottommost level with seqno=0.
