There is no advantage to using a Datum here. The Datum class is mainly
intended for representing something that might be a Scalar or might be an
Array.
> Also, is there an efficient way to loop through a slice perhaps by
incrementing a pointer?
You will want to cast the Array and avoid Scalar
On 2nd thoughts, the 2nd method could also be done in a single line.
auto low3 =
arrow::Datum(st_s_low.ValueOrDie()).scalar_as().value;
That said, I'm still keen to hear if there's an advantage to using Datum or
without; and on my 2nd question regarding efficiently looping through a
slice's
Hi
I'm trying to figure out the optimal way for extracting scalar values from
a table; I've found two ways, using a dynamic cast or using Datum and cast.
Is one better than the other? The advantage of the dynamic cast, seems at
least, to be a one liner.
auto c_val1 =
