---------------------------------------
wesm opened a new pull request #1297: WIP ARROW-1785: [Format/C++/Java] Remove
VectorLayout from serialized schemas
URL: https://github.com/apache/arrow/pull/1297
What's here so far removes this code from the Flatbuffers schema and the C++
implementation. This logic is a little bit entangled on the Java side, I need
some help from @icexelloss or @BryanCutler or @julienledem or someone else to
handle the Java refactoring. It might be easiest to preserve the
ArrowVectorType/TypeLayout/VectorLayout objects for now but simply remove the
Flatbuffers dependency (we do need the names of the vectors in the JSON files
used for integration testing)
cc @trxcllnt since we may want to roll in the JS changes in this patch

> [Format] Remove VectorLayout metadata from Flatbuffers metadata
> ---------------------------------------------------------------
>
> Key: ARROW-1785
> URL: https://issues.apache.org/jira/browse/ARROW-1785
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, Format, Java - Vectors
> Reporter: Wes McKinney
> Assignee: Wes McKinney
> Labels: pull-request-available
> Fix For: 0.8.0
>
>
> Based on the discussions on the mailing list, we should remove the
> VectorLayout metadata from the Flatbuffers spec for 0.8.0 since we are
> already breaking the metadata. We should instead make the buffer layouts an
> immutable part of the format specification so there is no ambiguity about
> what buffers accompany each type of field in an Arrow payload
> see also ARROW-1693
