type BoltSnapshotSink Uses

type BoltSnapshotSink struct {
    // contains filtered or unexported fields
}

BoltSnapshotSink implements SnapshotSink optionally choosing to write to a file.

func (*BoltSnapshotSink) Cancel Uses

func (s *BoltSnapshotSink) Cancel() error

func (*BoltSnapshotSink) Close Uses

func (s *BoltSnapshotSink) Close() error

func (*BoltSnapshotSink) ID Uses

func (s *BoltSnapshotSink) ID() string

func (*BoltSnapshotSink) Write Uses

func (s *BoltSnapshotSink) Write(b []byte) (int, error)

Write is used to append to the bolt file. The first call to write ensures we have the file created.

type BoltSnapshotStore Uses

type BoltSnapshotStore struct {
    // contains filtered or unexported fields
}

BoltSnapshotStore implements the SnapshotStore interface and allows snapshots to be stored in BoltDB files on local disk. Since we always have an up to date FSM we use a special snapshot ID to indicate that the snapshot can be pulled from the BoltDB file that is currently backing the FSM. This allows us to provide just-in-time snapshots without doing incremental data dumps.

When a snapshot is being installed on the node we will Create and Write data to it. This will cause the snapshot store to create a new BoltDB file and write the snapshot data to it. Then, we can simply rename the snapshot to the FSM's filename. This allows us to atomically install the snapshot and reduces the amount of disk i/o. Older snapshots are reaped on startup and before each subsequent snapshot write. This ensures we only have one snapshot on disk at a time.
