Struct rocksdb::IngestExternalFileOptions [−][src]
For configuring external files ingestion.
Examples
Move files instead of copying them:
use rocksdb::{DB, IngestExternalFileOptions, SstFileWriter, Options}; let writer_opts = Options::default(); let mut writer = SstFileWriter::create(&writer_opts); writer.open("_path_for_sst_file").unwrap(); writer.put(b"k1", b"v1").unwrap(); writer.finish().unwrap(); let path = "_path_for_rocksdb_storageY3"; { let db = DB::open_default(&path).unwrap(); let mut ingest_opts = IngestExternalFileOptions::default(); ingest_opts.set_move_files(true); db.ingest_external_file_opts(&ingest_opts, vec!["_path_for_sst_file"]).unwrap(); } let _ = DB::destroy(&Options::default(), path);
Implementations
impl IngestExternalFileOptions
[src]
pub fn set_move_files(&mut self, v: bool)
[src]
Can be set to true to move the files instead of copying them.
pub fn set_snapshot_consistency(&mut self, v: bool)
[src]
If set to false, an ingested file keys could appear in existing snapshots that where created before the file was ingested.
pub fn set_allow_global_seqno(&mut self, v: bool)
[src]
If set to false, IngestExternalFile() will fail if the file key range overlaps with existing keys or tombstones in the DB.
pub fn set_allow_blocking_flush(&mut self, v: bool)
[src]
If set to false and the file key range overlaps with the memtable key range (memtable flush required), IngestExternalFile will fail.
pub fn set_ingest_behind(&mut self, v: bool)
[src]
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.
