------------------------------------
Summary: [JS] Batch hint for Vector.get
Key: ARROW-1652
URL: https://issues.apache.org/jira/browse/ARROW-1652
Project: Apache Arrow
Issue Type: Improvement
Components: JavaScript
Reporter: Brian Hulette
The {{Vector.get}} function just accepts an index, and looks up the appropriate
record batch on every call. This can lead to a lot of additional lookups when
iterating by index. It would be nice if {{Vector.get}} accepted an optional
batch hint, similar to
[{{Vector.range}}|https://github.com/apache/arrow/blob/master/js/src/vector/typed.ts#L51]
Additionally, if {{Table}} had some knowledge of the batches in it's Vectors,
it could use this batch hint to improve performance when iterating over rows.
