示例1: buildDmlData

func (rowCache *InvalidationProcessor) buildDmlData(event *mysqlctl.UpdateResponse) (*proto.DmlType, error) {
	if !isDmlEvent(event.SqlType) {
		rowCache.updateErrCounters(NewInvalidationError(INVALID_EVENT, fmt.Sprintf("Bad Dml type, '%v'", event.SqlType), event.BinlogPosition.String()))
		return nil, nil
	}
	dml := new(proto.DmlType)
	dml.Table = event.TableName
	dml.Keys = make([]interface{}, 0, len(event.PkValues))
	sqlTypeKeys := make([]sqltypes.Value, 0, len(event.PkColNames))
	for _, pkTuple := range event.PkValues {
		sqlTypeKeys = sqlTypeKeys[:0]
		if len(pkTuple) == 0 {
			continue
		}
		for _, pkVal := range pkTuple {
			key, err := sqltypes.BuildValue(pkVal)
			if err != nil {
				rowCache.updateErrCounters(NewInvalidationError(INVALID_EVENT, fmt.Sprintf("Error building invalidation key '%v'", err), event.BinlogPosition.String()))
				return nil, nil
