Description

I'm writing an array of int32 to a byte buffer using an array.TableReader and  ipc.Writer. The array is  [1, 2, 3 (null), 4].

I then read it back from the byte buffer using an ipc.Reader.

If the chunk size of the array.TableReader is smaller than the size of the array, the null is ignored.

I read back `[1, 2,3, 4]`.

Is this a bug in my code or apache arrow?

Code attached.
