Hello Apache Arrow Team,
I am looking at ways my company can create an SDK that can share apache arrow
data while preserving table pivots. I was looking at how Pandas and Perspective
do it and it seems like
For row_pivots
Pandas just sorts the data into a flat arrow structure
Perspective actu
Awesome idea!
I would definitely either copy paste or link to Paul’s codepens of Arrow-JS
examples https://codepen.io/trxcllnt/pens/public
That’s basically how I know, how to use arrow-js.

P.S. Just a general thank you credit for Paul Taylor and his awesome work on
arrow-js and those
The documentation, from my understanding, is basically spread around
1. Within the actual files
https://github.com/apache/arrow/blob/master/js/src/table.ts#L118
2. Within the examples/unit test

Hello Team,
The docs for Custom Metadata in PyArrow say TODO
https://arrow.apache.org/docs/python/data.html#custom-schema-and-field-metadata
So I am wondering if someone has any example of adding some custom metadata to
PyArrow.
I tried looking through the pyarrow github repo and looking at the
Hey Team,
I noticed that under extension type the Arrow docs specifically call out to
`ARROW:extension:name` and `ARROW:extension:metadata` as recommended/reserved
metadata keys to handle extension types.
2 quick questions
1. Do the standard libraries handle that metadata key automaticall

Perspective uses arrow across the wire but internally uses it's own formats.

Arrow (which would probably include an analog of pandas' pivot_table), but
the query engine work is a prerequisite.

Hey Team,
Sorry if this is answered already somewhere I tried searching emails and issues
but couldn’t find anything. I am wondering if there is a standard way to encode
row or column pivots in Arrow?
I know Pandas does it already some way

Hello Everyone,
Some background. My name is Michael and I work at FactSet, which if you use
Arrow you may have heard because one of our architects did a talk on using
Arrow and Dremio.
