Class FsTemporarySnapshotWriter

java.lang.Object

io.zeebe.logstreams.impl.snapshot.fs.FsSnapshotWriter

io.zeebe.logstreams.impl.snapshot.fs.FsTemporarySnapshotWriter

All Implemented Interfaces:

SnapshotWriter

public class FsTemporarySnapshotWriter
extends FsSnapshotWriter

Extends FsSnapshotWriter, delegating the write of the checksum + data to it, and moving the data file to its correct path at the end.

In this respect, dataFile => temporaryFile, and snapshotFile is the correct final destination.
