-----------------------------------
Summary: [Format] Clarify language around buffer padding and
alignment in IPC
Key: ARROW-1224
URL: https://issues.apache.org/jira/browse/ARROW-1224
Project: Apache Arrow
Issue Type: Improvement
Components: Format
Reporter: Wes McKinney
Fix For: 0.6.0
We recommend 64-byte padding in memory allocations, but in practice some
systems may emit buffers that are only 8-byte aligned. We should take a look
through the format documents and perhaps indicate that 64-byte padding is the
_preferred_ padding but that 8-byte padding is the _required_ padding.
In particular, it should be clear that each buffer in an IPC payload must start
on an aligned 8-byte offset, but it does not necessarily need to be 64-byte
aligned.
