[jira] [Created] (ARROW-3212) [C++] Create deterministic IPC metadata

Wes McKinney created ARROW-3212:
-----------------------------------

             Summary: [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
             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.
