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.

Java is not particularly good at this kind of number crunching tasks.

Arena-Based Parsers
It may seem unexpected given all the hype around Go, but it is a surprisingly poor choice for this. If you want a more convenient language than C++ or Rust but retain the ability to reach optimal performance, C# could serve you much better.
Go underperforms at trivial XML parsing: https://news.ycombinator.com/item?id=40283721
If you push it, C# can extract optimal HW utilization when parsing text, beating C++: https://hotforknowledge.com/2024/01/13/1brc-in-dotnet-among-... (Go was not on the list because it was that much slower)

The One Billion Row Challenge in Go: from 1m45s to 4s in nine solutions
The more accurate statement would be is Go incapable of optimizations performed by Java and then Java is incapable of optimizations performed by C# and C++ implementations.
