{quote}I've gone through the documentation but I'm still unclear about the
usage of buffers with respect to arrays.
"A Buffer encapsulates a pointer and data size .... Buffers are untyped: they
simply denote a physical memory area"
"The central type in Arrow is the class arrow::Array. An array represents a
known-length sequence of values all having the same type. Internally, those
values are represented by one or several buffers ...."
The Array section then goes on to explain how to build Arrays with the
ArrayBuilder base class, and concrete subclasses. There doesn't appear to be
any need to allocate buffer space first. There is also a BufferBuilder class.
But since there does not appear to be a way associate a created buffer with an
array, I don't understand when explicit buffer creation would be used?
