Paul Taylor created ARROW-3337: ---------------------------------- Summary: JS writer doesn't serialize the dictionary of nested Vectors Key: ARROW-3337 URL: https://issues.apache.org/jira/browse/ARROW-3337 Project: Apache Arrow Issue Type: Improvement Components: JavaScript Affects Versions: JS-0.3.1 Reporter: Paul Taylor Assignee: Paul Taylor Fix For: JS-0.4.0
The JS writer only serializes dictionaries for [top-level children|https://github.com/apache/arrow/blob/ee9b1ba426e2f1f117cde8d8f4ba6fbe3be5674c/js/src/ipc/writer/binary.ts#L40] of a Table. This is wrong, and an oversight on my part. The fix here is to put the actual Dictionary vectors in the `schema.dictionaries` map instead of the dictionary fields, like I understand the C++ does. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
