Dmitri Bronnikov created ARROW-11326:
----------------------------------------
Summary: utf8 vector buffers don't work if allocated within Web
Assembly memory of Node.js
Key: ARROW-11326
URL: https://issues.apache.org/jira/browse/ARROW-11326
Project: Apache Arrow
Issue Type: Bug
Components: JavaScript
Environment: node.js in Mac book pro
Reporter: Dmitri Bronnikov
After making int32array of offsets = [0, 1] and uint8array of values
c[ascii_code('A')]create a vector of strings:
const vec = arrow.Vector.new(arrow.Data.new(new Utf8(), 0, 1, 0, [offsets,
values, null, null])
then access the first and only element:
console.log(vec.get(0))
Works within browsers. Works in node.js with fixed size types, e.g. float or
integer.
Fails in node.js with this callstack
