-------------------------------------
Summary: [JS] Arrow Tutorial: Common data types
Key: ARROW-7513
URL: https://issues.apache.org/jira/browse/ARROW-7513
Project: Apache Arrow
Issue Type: Task
Components: JavaScript
Reporter: Leo Meyerovich
Assignee: Leo Meyerovich
The JS client lacks basic introductory material around creating the common
basic data types such as turning JS arrays into ints, dicts, etc. There is no
equivalent of Python's [https://arrow.apache.org/docs/python/data.html] . This
has made use for myself difficult, and I bet for others.
As with prev tutorials, I started sketching on
[https://observablehq.com/@lmeyerov/rich-data-types-in-apache-arrow-js-efficient-data-tables-wit]
. When we're happy can make sense to export as an html or something to the
repo, or just link from the main readme.
I believe the target topics worth covering are:
* Common user data types: Ints, Dicts, Struct, Time
* Common column types: Data, Vector, Column
* Going from individual & arrays & buffers of JS values to Arrow-wrapped
forms, and basic inspection of the result
Not worth going into here is Tables vs. RecordBatches, which is the other
tutorial.
1. Ideas of what to add/edit/remove?
2. And anyone up for helping with discussion of Data vs. Vector, and ingest of
Time & Struct?
3. ... Should we be encouraging Struct or Map? I saw some PRs changing stuff
here.
