Documentation

Overview

Package state owns the replicator's local watermark file.

The file lives next to the database (default: /data/.zapdb-replicate- state.json). It records the most recent badger version successfully uploaded so a restart resumes the incremental stream where it left off without re-uploading the whole DB.

It is NOT the source of truth — that is the backend's HEAD.json. The state file is just a cheap local cache that lets the daemon skip re-listing the backend on each cycle.

Types

type State 

type State struct {
	Version           int       `json:"version"` // schema version (1)
	Network           string    `json:"network"`
	LastVersion       uint64    `json:"lastVersion"`       // badger watermark we last uploaded through
	LastSnapshotKind  string    `json:"lastSnapshotKind"`  // "full" | "increment"
	LastFullVersion   uint64    `json:"lastFullVersion"`   // watermark of the most recent full snapshot
	LastFullTimestamp time.Time `json:"lastFullTimestamp"` // when the last full snapshot ran
	UpdatedAt         time.Time `json:"updatedAt"`
}

State is the persisted replicator watermark.

func Load 

func Load(path string) (*State, error)

Load reads State from path. Returns a zero State (Version=1) if the file does not exist; any other error is wrapped.
