  • Run Flyway DB migrations with AWS Lambda and RDS - Part 1
    1 project | dev.to | 6 Jul 2024
    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
    1 project | dev.to | 17 Jun 2024
    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.

    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?
    5 projects | news.ycombinator.com | 14 Apr 2024
    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
    1 project | dev.to | 17 Dec 2023
    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
    4 projects | /r/dataengineering | 11 Jul 2023
    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
    2 projects | /r/java | 8 Jun 2023
    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).

  • H2 Database – CVE getting flagged by automated scans

  • “Our paying customers need X, when will you fix it?”
    5 projects | news.ycombinator.com | 15 Jul 2023
    This sounds very much like the idiocy of "infosec" lunkheads who know nothing about what they're "fixing" but if an automated system tells them a CVE exists, they've absolutely got to have it "patched". They don't look into what the claims of the CVE are, or whether their specific use case is vulnerable. They don't know, they don't care, they're not even programmers. All they know is a box needs ticking.

    A similar thing happened with h2database - a "security researcher" found that if you do something you're told not to do, then bad things happen.. but they demanded and got a CVE allocated anyway. Anyone who looks at it realises it's bullshit, but the mere existence of a CVE is all that matters to these idiots.

    What the h2database developer said about it: https://github.com/h2database/h2database/issues/3686#issueco...

    > I struggle to understand why I should feel the slightest shred of sympathy for "major corporations" that are using a volunteer-developed open-source project. Feel free to get your corporation to pay someone to deal with this, or pay for a similar commercial library.

    Firstly, let's set up a basic Spring Boot application. We can use the Spring Initializr with Spring Data JPA, H2 Database, Lombok added. H2 Database will provide us with a simple database, and Spring Data JPA will allow us to easily interact with it using Hibernate. Lombok will make it easier to write concise and readable classes.
  • Why are tar.xz files 15x smaller when using Python's tar compared to macOS tar?
    2 projects | news.ycombinator.com | 14 Mar 2021
    Sorting chunks by similarity: commonly used tools don't do that. Most archive tools only sort by file type.

    I wrote a tool that chunks the data (into variable-sized blocks, to re-sync if there are multiple files that have different length prefixes, but that's another story), and then sorts the chunks by LSH (locality sensitive hash). LSH is used by search engines to detect similar text. It can compress directories that contain multiple version of e.g. source code very well (e.g. trunk, branches). https://github.com/h2database/h2database/blob/master/h2/src/...

    I discussed this approach with a researcher in this area in January 2020. AFAIK there is active research in this area, specially to compress DNA sequences. But he also wasn't aware of papers or research in this area for general-purpose data compression.

    So, I think this area is largely uncharted. I would be interested (as a hobby side project) to help, if somebody is interested.
