Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tried polars in Ruby
6 projects | dev.to | 19 Jan 2023
Several members of the Ruby community have been deeply involved in the development of Apache Arrow.
IPC communication between rust, c++, and python
4 projects | reddit.com/r/rust | 30 Dec 2022
In that case, why not use polars, which supports apache arrow format which supports C, C++, Rust, Python and supports zero-copy read.
Introducing ArrowJS • Reactivity without the framework
I think the naming will likely cause some confusion with apache arrow. My initial thoughts when reading "Introducing ArrowJS" was a new port of the apache arrow spec.
Java Serialization with Protocol Buffers
6 projects | dev.to | 1 Nov 2022
The information can be stored in a database or as files, serialized in a standard format and with a schema agreed with your Data Engineering team. Depending on your information and requirements, it can be as simple as CSV, XML or JSON, or Big Data formats such as Parquet, Avro, ORC, Arrow, or message serialization formats like Protocol Buffers, FlatBuffers, MessagePack, Thrift, or Cap'n Proto.
GlueSQL: A SQL database engine written as a library in Rust
4 projects | news.ycombinator.com | 22 Oct 2022
Just another embedded SQL engine.
There are SQLite(OLTP), DuckDB(OLAP) and some engine-based project like mentioned Apache Arrow(https://arrow.apache.org/)(OLAP): Apache Arrow has many language implementations, some do not include the query engine(for example, Rust implementation, which depends on the DataFusion for more SQL-like analytics) in its own repo, but other do include(for example, C++).
There is a comprehensive benchmark by ClickHouse for OLAP but including kinds of embedding engines: https://benchmark.clickhouse.com/
The more interesting is that, in fact, we have not an embedded HTAP engine. One of my database products already implements 3/4 HTAP at the engine layer, but unfortunately it's still just a free software, not an open source implementation.

New Pandas-for-Haskell data frame library: Name suggestions

This is a meta-request for the library, but imo it would be really awesome if it used a data structure compatible with Arrow: https://arrow.apache.org/
How to Deploy ML Models Using Gravity AI and Meadowrun
4 projects | dev.to | 17 Aug 2022
As a bit of an aside, you could imagine a way to get the best of both worlds with an extension to Docker that would allow you to publish a container that exposes a Python API, so that someone could call sentiment = call_container_api(image="huggingface/transformers", "my input text") directly from their python code. This would effectively be a remote procedure call into a container that is not running as a service but instead spun up just for the purpose of executing a function on-demand. This feels like a really heavyweight approach to solving dependency hell, but if your libraries are using a cross-platform memory format (hello Apache Arrow!) under the covers, you could imagine doing some fun tricks like giving the container a read-only view into the caller’s memory space to reduce the overhead. It’s a bit implausible, but sometimes it’s helpful to sketch out these ideas to clarify the tradeoffs we’re making with the more practical bits of technology we have available.
