Functions

func ColumnsToProto

func ColumnsToProto(columns []*model.ColumnInfo, pkIsHandle bool) []*tipb.ColumnInfo

ColumnsToProto converts a slice of model.ColumnInfo to a slice of tipb.ColumnInfo.

func DecodeIndexKey

func DecodeIndexKey(key kv.Key) ([]types.Datum, error)

DecodeIndexKey decodes datums from an index key.

func DecodeRowKey

func DecodeRowKey(key kv.Key) (handle int64, err error)

DecodeRowKey decodes the key and gets the handle.

func DecodeValues

func DecodeValues(data []byte, fts []*types.FieldType, inIndex bool) ([]types.Datum, error)

DecodeValues decodes a byte slice into datums with column types.

func EncodeColumnKey

func EncodeColumnKey(tableID int64, handle int64, columnID int64) kv.Key

EncodeColumnKey encodes the table id, row handle and columnID into a kv.Key
