Magnum: A "New Look" for Scala 3 Database Clients

Magnum is a new database client utilizing the full power of Scala 3.

Its key innovation is combining macros and structural types to provide a typesafe, IDE-refactorable SQL interface, which can express all SQL expressions, on all JDBC-supported databases.

Database clients on the JVM fall into three categories.

  1. Object Oriented Repositories (Spring-Data, Hibernate)
  2. Functional DSLs (JOOQ, Slick, quill, zio-sql)
  3. SQL String interpolators (Anorm, doobie, plain jdbc)

This talk will highlight the pros and cons of each approach, and introduce Magnum, a new Scala 3 library combining aspects of all three. Both simple and advanced SQL queries will be compared, with an an emphasis on maintainability, ease of use, and performance.
