[jira] [Commented] (ARROW-7513) [JS] Arrow Tutorial: Common data
types
[ https://issues.apache.org/jira/browse/ARROW-7513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17010761#comment-17010761 ]
Brian Hulette commented on ARROW-7513:
--------------------------------------
Thanks for doing this Leo!
I just have one suggestion after a brief look this morning. I think Data should be considered a low-level API (and maybe even a private one?), and we should direct users to create Vectors directly with the builders, or with the {{from}} static initializers (which defer to the builders).
> [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
> Priority: Minor
>
> 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.
