-----------------------------------
Summary: Arrow file format writes record batches in reverse order.
Key: ARROW-395
URL: https://issues.apache.org/jira/browse/ARROW-395
Project: Apache Arrow
Issue Type: Bug
Reporter: Julien Le Dem
Assignee: Julien Le Dem
This is because flatbuffers require writing in reverse order and we don't for
record batches.
The following method:
org.apache.arrow.vector.file.ArrowFooter.endVector(FlatBufferBuilder,
List<ArrowBlock>)
Should use this one:
org.apache.arrow.vector.schema.FBSerializables.writeAllStructsToVector(FlatBufferBuilder,
List<? extends FBSerializable>)
