Sascha Hofmann updated ARROW-7109:
----------------------------------
Description:
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). In general wouldn't it be a nice to have
create Table from object function?
On another note, are there any plans to make the docs a little bit more
descriptive? Happy to contribute!
