> There were a couple patches related to 64-byte alignment for tensor messages
> at the beginning of April that I've been concerned about:
> ARROW-2308:
> https://github.com/apache/arrow/commit/26bc4ab5a31e3430e1d545068e5a5a5ba5bc7a22#diff-bf4eb56f3cb806c32f60ae67afbb1bf0

> https://github.com/apache/arrow/commit/0f87c12d45250ee763ac8c43b7e57e8f06a0b9f3
> In my opinion, the alignment issue should be encapsulated in the protocol if
> possible; to have argument that toggles whether the file is to be aligned
> after reading the metadata seems wrong to me. The bytes written for alignment
> purposes should be accounted for in the metadata size prefix in the IPC
> message.
> Since there are unit tests for this, I'd like to take a look and see if I can
> improve this without breaking the tests.
