Wes McKinney reassigned ARROW-3212:
-----------------------------------
Assignee: Wes McKinney
> [C++] Create deterministic IPC metadata
> ---------------------------------------
>
> Key: ARROW-3212
> URL: https://issues.apache.org/jira/browse/ARROW-3212
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Wes McKinney
> Assignee: Wes McKinney
> Priority: Major
> Fix For: 0.11.0
>
>
> Currently, the amount of padding bytes written after the IPC metadata header
> depends on the current position of the {{OutputStream}} passed. So if the
> message begins on an unaligned (not multiple of 8) offset, then the content
> of the metadata will be different than if it did. This seems like a leaky
> abstraction -- aligning the stream should probably be handled separately from
> writing the IPC protocol.
