Longevity Now Supports Querying with Akka Streams

I'm excited to announce longevity release 0.8, which features streaming queries with Akka Streams! Prior to this release, longevity queries returned a list of results wrapped in a future, which was sort of only half-way reactive, and definitely wouldn't work in the face of query results that were too large to fit into memory. I was never particularly happy with this, but I had enough to do at the time with designing and implementing the query DSL.


Longevity Release 0.7.0 - Entity Polymorphism

Longevity release 0.7.0 is out! The major focus of this release is support for entity polymorphism - that is, subtyping - in your domain model. This is a critical usability feature. It's also hopefully the last of what I might call "core features": those features that require me to go back and rework the core code of the longevity engine, consequently causing major ripple effects throughout the project. So this is a big release for me! It's a critical feature, and hopefully the last feature in a while that takes me a month to complete!

From the outside looking in, it may not seem like supporting subtyping in your domain model should be such a big deal. To understand why this is, I need to step back and discuss some of the key principles and design decisions I made in this project.
