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.

Run Flyway DB migrations with AWS Lambda and RDS - Part 1
Usually there is a need to run SQL database updates: update table columns, add new rows, create a new schema etc. Often developer teams are using Flyway It is an open-source database SQL deployment tool. In Flyway, all DDL and DML changes to the database are called migrations. Migrations can be versioned or repeatable.

A Journey Towards A Scalable Multi-Tenant Application
Our client's engineering team recommended Flyway and successfully used it to manage their migrations. We chose to adopt Flyway due to its simplicity, speed, reliability, and successful implementation by our client's engineering team. Their existing codebase and experiences allowed us to transition smoothly to Flyway.

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).

Ask HN: What tool(s) do you use to code review and deploy SQL scripts?
A regular code repo with the scripts (with pull/merge requests for review) and then a CI job that builds containers with something like dbmate https://github.com/amacneil/dbmate that can then be run against any staging/prod environment.

Level UP your RDBMS Productivity in GO
As we want to maintain the track of our changes to the DB, we are going to use migrations. In this case, we are going to use dbmate. But, you can use any other tool you want.

Rails 7.1 Released
> For example having database migrations built in etc.
I actually went the exact opposite route, at least when possible: https://github.com/amacneil/dbmate
Pure SQL migrations, regardless of the back end technology that you use, completely decoupled from how each framework/library views things and therefore not dependent on them (you could even rewrite the back end in another technology later on, if needed; or swap ORMs; or avoid issues when there's a major ORM version update).
It's really nice when you can generate entity mappings based on a live database, like with https://blog.jetbrains.com/dotnet/2022/01/31/entity-framewor...
So in my case, I can have:
* a DB that has migrations applied with dbmate, completely decoupled from any back end(s) that might use it

How do your teams run DB migrations?
You can run dbmate as part of your CI/CD pipeline. You just keep a dbmate directory in your repo and deploy migrations with your code.

Working with TypeORM 0.3x with Nestjs - I wasn't aware so many people were facing issues with it
In general with ORMs, you will face a problem in one way or another. I ended up simply using https://github.com/gajus/slonik and https://github.com/amacneil/dbmate for migrations. My life is way much better since then.
