Types

type StoreBehavior

type StoreBehavior uint8

StoreBehavior is the action to do in GetAllTiKVStores when a non-TiKV store (e.g. TiFlash store) is found.

const (
	// ErrorOnTiFlash causes GetAllTiKVStores to return error when the store is
	// found to be a TiFlash node.
	ErrorOnTiFlash StoreBehavior = 0
	// SkipTiFlash causes GetAllTiKVStores to skip the store when it is found to
	// be a TiFlash node.
	SkipTiFlash StoreBehavior = 1
	// TiFlashOnly caused GetAllTiKVStores to skip the store which is not a
	// TiFlash node.
	TiFlashOnly StoreBehavior = 2
