parquet-tools
This go implementation, other than common advantages from go itself (small single executable, support multiple platforms, speed, etc.), has some neat features compare with Java parquet tool and Python one like:

Writing Apache Parquet Files
Hi, I've been trying to write parquet files on android for the past couple of days, and have really been struggling to find a solution. My original hypothesis was to just use the java parquet implementation (https://github.com/apache/parquet-mr), but I've since realized that not all java libraries play well with Android. I've gone through essentially dependency hell trying to franken-fit the library into my project, and imported as much as i could before hitting walls such as this one (https://github.com/mockito/mockito/issues/841).

pqrs: A parquet-tools replacement in Rust using Apache Arrow
Like many of you probably do, I tend to work with Parquet files a lot. parquet-tools has been my tool of choice for inspecting parquet files, but that has been deprecated recently. So, I created a replacement for it using Rust and Apache Arrow.

Possibly stupid question, is java the right language for low latency and high throughput web servers?
I was about to suggest Chronicle, but it looks like they have gone closed-source. The older version is still interesting to look through though. Aeron / Disruptor / SBE are good projects for inspiration as well.

GitHub - realtimetech-solution/opack: Fast object or data serialize and deserialize library
Could you evaluate how it compares with SBE?

Simple Binary Encoding (SBE) now supports Rust
The Simple Binary Encoding (SBE) project now includes support for generating Rust code. Generated code produced does not use unsafe and has no dependencies on any other crates.

I made an NBT-based data format, but a little more general purpose

Parsing Protobuf at 2+GB/S: How I Learned to Love Tail Calls in C
Consider a valid protobuf message with such a field. If you can locate the field value bytes, you can write a new value to the same location without breaking the message. It's obviously possible to the same with the varint type too, as long as you don't change the number of bytes - not so practical, but useful for enum field which has a limited set of useful values (usually less than 128).
Pregenerating protobuf messages you want to send and then modifying the bytes in-place before sending is going to give you a nice performance boost over "normal" protobuf serialization. It can be useful if you need to be protobuf compatible, but it's obviously better to use something like SBE - https://github.com/real-logic/simple-binary-encoding
