Hi community,

I just drafted a variant blog
.
When you have time, can you help review?

Thanks,

Re: [DISCUSS] Parquet blog

[Andrew Lamb]

The idea of blog posts came up the other day too, so I filed some tickets
to hopefully track and organize the effort and help collaboration

I think there are at least three proposed blogs in this thread, so I filed
three tickets:

- Variant[1]
- Geospatial[2]
- Complex Types[3]

Looking forward to seeing these get posted. Let me know how I can help
(e.g. figuring out how to actually post them on the site, for example).

Re: [DISCUSS] Parquet blog

[Arnav Balyan]

Just noticed Julien mentioned having one doc per topic. To clarify, this
one is for Nested (Complex) Data Types specifically .I’ve renamed the doc
to focus only on Nested (Complex) Data types so it’s scoped properly.
Link (same access):
https://docs.google.com/document/d/1cx61Fp82HHB8TvePO4bFIbX1EXvv9Sy8Wx_YnyKeeW8/edit?tab=t.0

Please feel free to comment or suggest edits. Thanks!

Re: [DISCUSS] Parquet blog

[Julien Le Dem]

All we need is someone to start a draft on a google doc and share it on the
list to start collaborating :)
(for each article)
Thank you everyone who's chiming in.

Thanks, Julien.

I will start a google doc about the Parquet Geo type blog! I will also
ping Dewey for some help.

Hi Julien and all,

+1 - I’d be happy to contribute a short write-up on how Parquet handles complex 
nested data types.

Thanks Jia and Dewey!

I wasn’t sure if we planned to have separate docs or a shared one, I just
put up this one to get things started. Please feel free to add your content

Re: [DISCUSS] Parquet blog

[Andrew Lamb]

I think writing up some of the recent progress in Parquet is a great idea
and I think will help the project to continue to grow and evolve.  I am
happy to collaborate on any of the topics listed so far.

Another post that might be interesting is be something like this:

"The future of Parquet: Calling for Ideas" that makes a broad, public call
for people to come join the conversation and help us understand how they
would like to see the format evolve.  We could also highlight the recent
documentation of the proposal structure / process.

Re: [DISCUSS] Parquet blog

[Julien Le Dem]

I think the best way would be to coordinate on the list in case more than
one person wants to contribute on the same topic.
If that happens, you could either collaborate on a blog post with multiple
authors or have two posts with different angles.
We can use google docs as working documents shared on the list where people
can contribute suggestions or comments.
We can even use github issues for blog posts we'd like to see.
