Скачать или смотреть How Reddit Migrated Their Highest-Traffic Service from Python to Go

Reddit migrated their highest-traffic service (comments) from a legacy Python monolith to a dedicated Go microservice. The results? Significant latency improvements and better scalability.

What I cover:
The "tap compare" strategy for safe migrations
Sister datastore pattern for zero-downtime cutover
Why they chose Go over sticking with Python
Latency and performance results
Lessons learned from migrating write endpoints at scale

This is one of the better engineering blog posts I've read on large-scale migrations. If you're considering moving services between languages or breaking up a monolith, there's a lot to learn here.
