Method ToMap

pkg/parquetquery/iters.go:242–248

ToMap converts the unstructured list of data into a map containing an entry for each column, and the lists of values. The order of columns is not preseved, but the order of values within each column is.

()

// for each column, and the lists of values.  The order of columns is
// not preseved, but the order of values within each column is.
func (r *IteratorResult) ToMap() map[string][]pq.Value {
	m := map[string][]pq.Value{}
	for _, e := range r.Entries {
		m[e.Key] = append(m[e.Key], e.Value)
	}
	return m
}

// Columns gets the values for each named column. The order of returned values
// matches the order of names given. This is more efficient than converting to a map.
