Lessons from a Rushed Scala 2.13 to Scala 3 Migration: Performance Challenges in Data Ingestion Services
By

A respectable bake. You'd come back tomorrow for another.
Summary
The article discusses a developer's experience migrating a service from Scala 2.13 to Scala 3, focusing on performance challenges encountered during a rushed migration. While the author had generally positive experiences with Scala 3 migrations in the past, this particular project involved a data ingestion service where performance was critical. The article shares lessons learned from the migration process, emphasizing that the slowdown wasn't due to the language or compiler itself, but rather the rushed nature of the migration and specific project characteristics.

· 4 pulledIs this clickbait? Not really. Is this the fault of the language or the compiler? Definitely not. Rather, it was part of a rushed migration. Sharing the lessons learned in the process.
I was refreshing one of our services. Part of this process was to migrate codebase from Scala 2.13 to Scala 3. I've done this a few times before and overall had a positive experience.
The service in question had no macros at all, but it was at the heart of data ingestion, so performance was not an afterthought.
Well, at least until we talk about projects with macro wizardry.
