  Language-Natural Persistence Layer for Java

  

Ok, let's change to that from https://permazen.io/ above.

Usually we go the other way and prefer the project page, but there's clearly not enough info there.

• JDBI

  27 1,901 9.4 Java

  The Jdbi library provides convenient, idiomatic access to relational databases in Java and other JVM technologies such as Kotlin, Clojure or Scala.

  

Someone else mentioned jOOQ, but personally I also rather enjoyed JDBI3: https://jdbi.org/#_introduction_to_jdbi_3

It addresses the issues with using JDBC directly (not nice ergonomics), while still letting you work with SQL directly without too many abstractions in the middle. In combination with Dropwizard, it was pretty pleasant: https://www.dropwizard.io/en/stable/manual/jdbi3.html

Other than that, I actually liked using myBatis with XML mappers: https://mybatis.org/mybatis-3/sqlmap-xml.html and their dynamic functionality: https://mybatis.org/mybatis-3/dynamic-sql.html

It might sound a bit of crazy on the surface, but their DSL actually made sense and was intertwined with the SQL you wrote, a bit like templating that you might use for front end stuff, except that directly for your database queries. It was great for adding complex WHERE parts for specific filters or re-using parts of queries.

• MapDB

  5 4,832 0.0 Java

  MapDB provides concurrent Maps, Sets and Queues backed by disk storage or off-heap-memory. It is a fast and easy to use embedded Java database engine.

So, it's an object database, like Zope's ZODB on Python?

I like the idea, but I'd like to learn about use cases for it.

Otherwise, in Java, MapDB is about as far as I'd be willing to go: https://github.com/jankotek/mapdb/

• microstream

Personally, I found https://microstream.one/ interesting for simple persistance needs (haven't tried it, though).
