### 讨论详情
## Description
The current implementation of `BaseExecutor.parsePkValues` uses a very
brute-force three nested for loops, and its time complexity needs to be
optimized.
```go
func (b *BaseExecutor) parsePkValues(rows []types.RowImage, pkNameList
[]string) map[string][]types.ColumnImage {
pkValues := make(map[string][]types.ColumnImage)
// todo optimize 3 fors
for _, row := range rows {
for _, column := range row.Columns {
for _, pk := range pkNameList {
if strings.EqualFold(pk, column.ColumnName) {
values := pkValues[strings.ToUpper(pk)]
if values == nil {
values =
make([]types.ColumnImage, 0)
}
values = append(values, column)
pkValues[pk] = values
}
}
}
}
return pkValues
}
```
