> [Java] ArrowStreamWriter accumulates ArrowBlock but does not use them
> ---------------------------------------------------------------------
>
> Key: ARROW-2632
> URL: https://issues.apache.org/jira/browse/ARROW-2632
> Project: Apache Arrow
> Issue Type: Bug
> Components: Java
> Reporter: Eric Wohlstadter
> Assignee: Teddy Choi
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.10.0

> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> {{ArrowStreamWriter}} inherits from {{ArrowWriter}} the behavior of
> accumulating an {{ArrowBlock}} for each {{ArrowRecordBatch}} that is written.
> But this data is never used in the context of {{ArrowStreamWriter}}.
> {code:java}
> public abstract class ArrowWriter implements AutoCloseable {
> private final List<ArrowBlock> recordBlocks = new ArrayList<>();
> ...
> protected void writeRecordBatch(ArrowRecordBatch batch) {
> ...
> recordBlocks.add(block);
> }
> }
> {code}
> {{writeRecordBatch}} can be overridden in {{ArrowStreamWriter}} to avoid
> adding the memory overhead.
