Is your feature request related to a problem or challenge? Please describe what you are trying to do.

• part of Release arrow-rs / parquet Major version 57.0.0 (October 2025) #7835

Describe the solution you'd like
Quoting @pauldix the cofounder and CTO of InfluxData, the recipe for success is:

1. write great software
2. Tell people about it

There are some pretty major events going on in arrow-rs that I think it would be great to tell people about:

1. Experimental variant support [EPIC] [Parquet] Implement Variant type support in Parquet #6736 with @scovich @klion26 @liamzwbao @codephage2020 and others: Blog post about Variant support #8566
2. Avro support (see Blog post about adding arrow-avro #8428 ) from @jecsand838 and @nathanielc
3. Rewritten metadata parsing from @etseidl Use custom thrift decoder to improve speed of parsing parquet metadata #5854
4. Parquet push decoder (along with metadata decoder, hopefully) Decouple IO and CPU operations in the Parquet Reader (push decoder) #7983

It would be great to have a writeup / public announcement about this great new feature on the arrow blog https://arrow.apache.org/blog/
