Overview ¶

Package badger snapshots and loads a whole Badger instance for the platform stores built on one (ADR-0202), the metastore engine and the run state, so each reads in one transaction alike.

Index ¶

func Load(ctx context.Context, db *badger.DB, next func() (snapshot.Record, error), ...) error
func Snapshot(ctx context.Context, db *badger.DB, emit func(snapshot.Record) error) error
func SnapshotPrefix(ctx context.Context, db *badger.DB, prefix []byte, ...) error

Functions ¶

func Load ¶

func Load(ctx context.Context, db *badger.DB, next func() (snapshot.Record, error), skip func(key []byte) (bool, error)) error

Load writes the records next returns, until io.EOF, into db through a WriteBatch, which commits whenever Badger's transaction limit is reached. A non-empty db gets fault.Conflict before any write. skip, when not nil, names a record to leave out, or fails the Load on a malformed one.

func Snapshot ¶

func Snapshot(ctx context.Context, db *badger.DB, emit func(snapshot.Record) error) error

Snapshot emits every key and its latest value, in key order, from ONE read transaction with ONE iterator: never DB.Backup or a Stream, whose producers each read at their own time (#806).

func SnapshotPrefix ¶

func SnapshotPrefix(ctx context.Context, db *badger.DB, prefix []byte, emit func(snapshot.Record) error) error

SnapshotPrefix is Snapshot over the keys under prefix, each emitted without it (ADR-0209 Decision 7).
