buffer

Documentation

Overview

Package buffer provides a sorted.KeyValue implementation that buffers one KeyValue implementation in front of an another. It's used for cases such as reindexing where you need a KeyValue but it doesn't need to be flushed and consistent until the end.

Types

type KeyValue

type KeyValue struct {
	// contains filtered or unexported fields
}

func New

func New(buffer, backing sorted.KeyValue, maxBufferBytes int64) *KeyValue

New returnes a sorted.KeyValue implementation that adds a Flush method to flush the buffer to the backing storage. A flush will also be performed when maxBufferBytes are reached. If maxBufferBytes <= 0, no automatic flushing is performed.
