Brian Hulette created ARROW-1652: ------------------------------------ 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
