-------------------------------------
Summary: [JS] Create table from Arrays
Key: ARROW-7109
URL: https://issues.apache.org/jira/browse/ARROW-7109
Project: Apache Arrow
Issue Type: Wish
Reporter: Sascha Hofmann
I am trying to generate an arrow table from JS arrays and followed the example
from
[here|[https://observablehq.com/@lmeyerov/manipulating-flat-arrays-arrow-style]]
but I am struggling to generate different schemas, most importantly how to
provide a type different then 'floatingpoint'. Right now, I have:
{code:java}
const data = Table.from({ schema: { fields: [ { name:
'a', nullable: false, children: Array(0), type: {
name: 'floatingpoint', precision: 'SINGLE' }
} ] }, batches: [ { count: 10, columns: [
{ name: 'a', count: 10, VALIDITY: [], DATA: Array.from({ length: 10 }, () =>
'a') } ] } ] })
{code}
Which, of course is non-sense but I couldn't figure out how to provide the type
(I tried type: Utf8 among others).
On another note, are there any plans to make the docs a little bit more
descriptive? Happy to contribute!
