### Describe the usage question you have. Please include as many useful
details as possible.
I want to do some record splitting/merging based on the size, but didn't
find a reliable way to estimate the size.
There are two ways:
```
for _, col := range rec.Columns() {
for _, buffer := range col.Data().Buffers() {
if buffer != nil {
bytes += uint64(buffer.Cap())
}
}
```}
or
```
func computeColumnSize(col arrow.Array) uint64 {
switch colType := col.DataType().(type) {
case arrow.BinaryDataType:
switch arr := col.(type) {
case *array.String:
return uint64(arr.ValueOffset(arr.Len()) -
arr.ValueOffset(0))
// ...
}
}
}
```
I'm wondering what's the recommended way to compute the size of
`arrow.Record`.
