1BRC Merykitty's Magic SWAR: 8 Lines of Code Explained in 3k Words
What an amazing step by step explanation!
More than 2 years ago I found that byte array view var handles are quite suitable to cook efficient SWAR routines with Java/Scala.
See a lot of other examples of SWAR usage, like parsing Base16/64 string, java.time.* and number values directly from byte arrays:

The Newest Java Json Benchmark Results just dropped
Afaik dsl-json came up with a lot of improvements and inspired a several other libraries like JsonIter and jsonIter-scala. Jsoniter-scala by u/plokhotnyuk is probably the most optimized JSON library on the JVM at this point, and seems to power most of the Scala ecosystem. Some implementations/optimizations eventually made their way back into Jackson and other libraries.

Please try my JSON library
I was on your place more then 5 years ago, when cut the 1st release of jsoniter-scala.

Post your problems with Scala 3/2.13 compiler performance!
I've just increased compiler performance in ~1.5x times by adding these JVM options for the code cache

smithy-translate : a CLI tool to turn openapi specs and json-schema specs into smithy specs, written in Scala
We have our own open-source code-generator that produces Scala code from Smithy. The code module is entirely dependency-free, and the generated code is not biased towards any library, be that http or json. We do however have out-of-the-box integration with jsoniter and http4s.
-
Why does Scala seem to be slow at benchmark results?
You can use jsoniter-scala. It is easy to use like upickle.
-
Scala needs *highly* efficient libraries to survive in a multi-core age
BTW, jsoniter-scala uses it for faster parsing and serialization using SWAR techniques, like here.

Using Circe with GADT
Probably you should have both codecs (for Foo and for its T) are implicitly available in the scope, like it is done in the following test for jsoniter-scala:

Starting with scala
BEWARE: uJson is vulnerable under DoS attacks

Is Scala a good choice for a data intensive web backend?
Please see sources (and GitHub history of development) of jsoniter-scala as an example in the domain of JSON parsing and serialization.

Is Li Haoyi libs standard throught scala useres?
To dive into the lihaoyi ecosystem, I recommend the book https://www.handsonscala.com/ by lihaoyi himself.
-
Contrary to popular belief, Scala is actually a quite small and simple language
I recommend people go through Hands-on Scala, by Li Haoyi, a fantastic developer in the Scala community.
-
Good book for non-beginners in programming
The best practical book around Scala language features is https://www.handsonscala.com/

How is Databricks' style guide viewed nowadays?
If you like Li Haoyi's style of Scala, his book is a good place to start (it's longer than just a Style guide, of course): https://www.handsonscala.com/

Algorithms and Data Structures in Scala;
is there a great resource, book or libraryā€¨ on classic Algorithms and Data Structures in Scala, e.g. similar in scope and quality to Sedgewick Algorithms in Java https://algs4.cs.princeton.edu/home/ I found a very helpful section on algorithms implementation in /u/lihaoyi superb Hand-On Scala Programming book , but unfortunately it's only a few pages (p.107-121). And most other books provide algorithms just an illustration for some neat language feature. The thing is, to get a job as Scala developer these days (in competitive firms) one needs to be a competitive programmer, master of Leetcode, and Scala doesn't seem to have strong ecosystem in that regard as Java, Python or C++. Edit: in DIY spirit and as a learning exercise i'm thinking of translating Sedgewick Algorithms from Java to idiomatic functional Scala, if anyone wants to join this effort or aware of similar ones please let me know Edit 2 (in regards to comments on 'reinventing the wheel' below): if Scala is so great as a language and functional programming flagship, where are all the libraries of functionally implemented algorithms replacing conventional CLRS style imperative/mutable implementations?

Need suggestions on where and how I can practice functional programming with Scala or in general programming in Scala. New to Scala.
handsonscala is a great read for programming in general using scala. Especially if you're the practical kind of learner.

Scala at Scale at Databricks
I will toot the author's horn for him. He has a great series of Scala posts on his blog [1] and his book Hands-On Scala Programming [2] is a great introduction to building real applications with Scala so that any experienced developer can understand and extend them.
I work at a small company that has been using Scala for 7 years. Some of the prior employees clearly enjoyed playing with advanced language features and writing libraries for the most general possible case even when that made it hard to understand how they were used for the 2 actual cases we needed to address in our application code. Akka, Cats, and Shapeless were all over the place.
Those earlier employees have churned off to other places and I have successively simplified the code they wrote that is still useful, while encouraging the use of no more language power than necessary in new development. Hands-On Scala Programming is the book I give new hires as a language introduction that shows the sort of style to be preferred. It's much more like super-powered Python than like Haskell.
I have written C, JavaScript, Python, and Scala for money. When I started on Scala I had never written Java nor used any JVM language. I have come to really appreciate the rich ecosystem of JVM libraries, the instrumentation and profiling tools I get, and many aspects of the Scala language and standard library. I love Scala's collections and miss their power and ease when I'm writing Python. (Which I still do for certain scripting tasks and for accessing Python-ecosystem libraries.)
