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.

Javalin – a simple web framework for Java and Kotlin
Micronaut has a share of the space too.
https://micronaut.io/
However, you’re right that Spring Boot has the lions share of the Java ecosystem.

Spark – A web micro framework for Java and Kotlin
I've used vert.x in a big project once. I don't ever want to do that again. Performance is pretty good, but the developer experience is beyond clunky.
My current favourite Java server framework is Micronaut.
Great performance and easy to develop for!

Java consumes 38x less energy than Python
I wonder how much you'd save with Micronaut: https://micronaut.io/
> Micronaut is a software framework for the Java virtual machine platform. It is designed to avoid reflection, thus reducing memory consumption and improving start times. Features which would typically be implemented at run-time are instead pre-computed at compile time.
https://en.wikipedia.org/wiki/Micronaut_(framework)
I don't think you'd go down to 9, but something like 20-30 could be doable.

mlfx FXML compiler
I'd like to introduce my project. It is called mlfx. It can compile FXML ahead of time. It is basically an annotation processor, which internally uses Micronaut framework's AST abstraction and compiles fxml files directly to JVM bytecode. This decreases UI load time and also helps with native-image reflection configs. It also has some compliance tests that load compiled code and check resulting object graph against one loaded by javafx-xml. It also has some drawbacks now, but, please, read README. Now I'm successfully using it in two production projects.

Tech-stack for web application using Kotlin?
For the server Quarkus and Micronaut might be interesting besides Spring Boot. Quarkus is more popular and backed by RedHat (so probably here to stay).

Would love some guidance in how to get started with building web projects with Java.
Spring boot is still The King. Although I've not done more than hello world with Micronaut, it might have easier learning curve than Spring (and concepts are similar to Spring so you can carry over later to learn Spring). It could also be a useful skill in world of microservices these days.

Let's write a simple microservice in Clojure
The session logs show that the application loads configurations and establishes a connection with a PostgreSQL database. This involves initializing a HikariCP connection pool and Flyway for database migrations. The logs confirm that the database schema validation and migration checks were successful. The startup of the Jetty HTTP server follows, and the server becomes operational and ready to accept requests on the specified port.

Ask HN: What tool(s) do you use to code review and deploy SQL scripts?
Also RedGate, but Flyway has some reasons to recommend it over RedGate Deploy depending on your DBAs/workflows: https://flywaydb.org/
(Though I don't think it is "complete" or "perfect", either.)
EF Migrations are in a really good place now if you like/don't mind C# as a language (and you can easily embed SQL inside the C#, too, but there are benefits to being able to also run high level C# code). With today's tooling you can package your migration "runner application" as a single deployable executable for most platforms. You can build the executable once and run it in all your environments. (The same tool that updates your QA and Staging updates your Prod, testably running the same migrations.) Given the single executable deployable I might even consider using it for projects not themselves written in C#.

PostgreSQL Is Enough
There is a bit of tooling needed but is already around. For Java for example I had very good experience with a combination of flyway [1] for migrations, testcontainers [2] for making integration tests as easy as unit tests and querydsl [3] for a query and mapping layer.

Using Flyway to version your database
When software starts using a database, it's advisable to have version control, just as we have Github to control our source code. This is all to be sure about what was executed for that specific version. For Java and Spring boot, we have the Flyway framework that aims to resolve this situation, free of charge.

CI/CD for Databricks
If you're looking for tools, like https://www.liquibase.com/ or https://flywaydb.org/, which are database-state-based schema migration toolkits - it might be relatively straightforward to build similar ones using Databricks SQL drivers.

Working with jOOQ and Flyway using Testcontainers
Honestly I kind of wish there was a Lukas Eder database migration library. Call it whatever jooq-migration. At least I would have more insight of what is going on (<-- seriously look at the commit history).

Strategy to run database scripts on Kubernetes
This is a 4th option, which should play nice with ArgoCD. The following example runs flyway as a k8s job. The desired migration changes are recorded as files within the chart. This helm chart can be integrated with your application (Using hooks to determine when the migration job is run) or run manually.
-
How do your teams run DB migrations?
By using an opinionated framework within the app/service (like Flyway, Migrate, Diesel, etc). Schema migrations happen on app/service start-up.
-
I've never created a production database from scratch and am wondering how much trouble it would be to transition a one-to-one relationship to a one-to-many relationship if I determine at some point that the latter is required.
Depending on the language or platform there are libraries you can use to manage this, such as Prisma on node and Flyway for Java/JVM.
-
How should I document and/or automate schema changes?
It's probably overkill but I've used github plus flyway at a couple places in the past which is pretty nice tool for tracking changes to a variety of db's, it's also very helpful if you ever need to replicate a db in a new region/environment.
