var TempTableFromMeta func(tblInfo *model.TableInfo) TempTable

TempTableFromMeta builds a TempTable from *model.TableInfo. Currently, it is assigned to tables.TempTableFromMeta in tidb package's init function.

Types

type TempTable

type TempTable interface {
	// GetAutoIDAllocator gets the autoID allocator of this table.
	GetAutoIDAllocator() autoid.Allocator

	// SetModified sets that the table is modified.
	SetModified(bool)

	// GetModified queries whether the table is modified.
	GetModified() bool

	// The stats of this table (*statistics.Table).
	// Define the return type as interface{} here to avoid cycle imports.
	GetStats() interface{}

	GetSize() int64
	SetSize(int64)

	GetMeta() *model.TableInfo
}

TempTable is used to store transaction-specific or session-specific information for global / local temporary tables. For example, stats and autoID should have their own copies of data, instead of being shared by all sessions.
