Types

type FileBackend

type FileBackend struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

FileBackend is a physical backend that stores data on disk at a given file path. It can be used for durable single server situations, or to develop locally where durability is not critical.

WARNING: the file backend implementation is currently extremely unsafe and non-performant. It is meant mostly for local testing and development. It can be improved in the future.
