	// before the node began accepting writes.
	SortedCommitLogFiles []string
}

func InspectFilesystem 

func InspectFilesystem(fsOpts Options) (Inspection, error)

InspectFilesystem scans the filesystem and generates a Inspection which the commitlog bootstrapper needs to avoid reading commitlog files that were written *after* the process has already started. I.E in order to distinguish between files that were already on disk before the process started, and those that were written by the process itself once it started accepting writes (but before bootstrapping had complete) we export a function which can be called during node startup.

	EvalTrue
	// EvalFalse indicates the boolean has been evaluated to false.
	EvalFalse
)

		seriesID ident.ID,
		blockStart xtime.UnixNano,
		nsCtx namespace.Context,
	) ([]xio.BlockReader, bool, error)

	// ForEachRemaining loops through each seriesID/blockStart combination that
	// was not already handled by a call to Read().
	ForEachRemaining(
		ctx context.Context,
		blockStart xtime.UnixNano,
		fn ForEachRemainingFn,
		nsCtx namespace.Context,
	) error
}

MergeWith is an interface that the fs merger uses to merge data with.

func NewNoopMergeWith added in v0.15.10 

func NewNoopMergeWith() MergeWith

NewNoopMergeWith creates a new noopMergeWith object. NoopMergeWith can be used in conjunction with the merge.Merger to generate copies of filesets.

type Merger added in v0.10.0 

type Merger interface {
	// Merge merges the specified fileset file with a merge target.
	Merge(
		fileID FileSetFileIdentifier,
		mergeWith MergeWith,
		nextVolumeIndex int,
		flushPreparer persist.FlushPreparer,
		nsCtx namespace.Context,
		onFlush persist.OnFlushSeries,
	) (persist.DataCloser, error)

	// MergeAndCleanup merges the specified fileset file with a merge target and removes the previous version of the
	// fileset. This should only be called within the bootstrapper. Any other file deletions outside of the bootstrapper
	// should be handled by the CleanupManager.
	MergeAndCleanup(
		fileID FileSetFileIdentifier,
		mergeWith MergeWith,
		nextVolumeIndex int,
		flushPreparer persist.FlushPreparer,
		nsCtx namespace.Context,
		onFlush persist.OnFlushSeries,
		isBootstrapped bool,
	) error
}

	identPool ident.Pool,
	encoderPool encoding.EncoderPool,
	contextPool context.Pool,
	filePathPrefix string,
	nsOpts namespace.Options,
) Merger

NewMerger returns a new Merger. This implementation is in charge of merging the data from an existing fileset with a merge target. If data for a series at a timestamp exists both on disk and the merge target, data from the merge target will be used. This merged data is then persisted.

Note that the merger does not know how or where this merged data is persisted since it just uses the flushPreparer that is passed in. Further, it does not signal to the database of the existence of the newly persisted data, nor does it clean up the original fileset.
