> 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!
