Golang leveldb_create_snapshot Examples

Example #1

File: db.go Project: rechen/wharf

func (db *DB) NewSnapshot() (driver.ISnapshot, error) {
	snap := &Snapshot{
		db:           db,
		snap:         C.leveldb_create_snapshot(db.db),
		readOpts:     NewReadOptions(),
		iteratorOpts: NewReadOptions(),
	}
	snap.readOpts.SetSnapshot(snap)
	snap.iteratorOpts.SetSnapshot(snap)
	snap.iteratorOpts.SetFillCache(false)

	return snap, nil
}

Example #2

File: db.go Project: Eddie0330/ledisdb

func (db *DB) NewSnapshot() *Snapshot {
	s := &Snapshot{
		db:           db,
		snap:         C.leveldb_create_snapshot(db.db),
		readOpts:     NewReadOptions(),
		iteratorOpts: NewReadOptions(),
	}

	s.readOpts.SetSnapshot(s)
	s.iteratorOpts.SetSnapshot(s)
	s.iteratorOpts.SetFillCache(false)

	return s
}

Example #3

File: db.go Project: olehz/hyperleveldb-go

// NewSnapshot creates a new snapshot of the database.
//
// The snapshot, when used in a ReadOptions, provides a consistent view of
// state of the database at the the snapshot was created.
//
// To prevent memory leaks and resource strain in the database, the snapshot
// returned must be released with DB.ReleaseSnapshot method on the DB that
// created it.
//
// See the LevelDB documentation for details.
func (db *DB) NewSnapshot() *Snapshot {
	return &Snapshot{C.leveldb_create_snapshot(db.Ldb)}
}

Example #4

File: db.go Project: andradeandrey/levigo

// NewSnapshot creates a new snapshot of the database.
//
// The snapshot, when used in a ReadOptions, provides a consistent view of
// state of the database at the the snapshot was created.
//
// To prevent memory leaks and resource strain in the database, the snapshot
// returned must be released with this DB's ReleaseSnapshot() method.
//
// See the LevelDB C++ documentation docs for details.
func (db *DB) NewSnapshot() *C.leveldb_snapshot_t {
	return C.leveldb_create_snapshot(db.Ldb)
