Types

type BatchStore

type BatchStore interface {
	store.StoreReader

	// WriteBatch atomically writes a list of write operations to the database.

	// Close closes the store.
	Close() error

	// NewSnapshot creates a snapshot.
	NewSnapshot() store.Snapshot
}

BatchStore is a CRUD-capable storage engine that supports atomic batch writes. BatchStore doesn't support transactions. This interface is a Go version of the C++ LevelDB interface. It serves as an intermediate interface between store.Store and the LevelDB interface.

type WriteOp struct {
	T     WriteType
	Key   []byte
	Value []byte
}

type WriteType

type WriteType int

	PutOp WriteType = iota
	DeleteOp
)
