At Reddit, we have four Core Models that power pretty much all use cases: Comments, Accounts, Posts and Subreddits. These four models were being served out of a legacy Python service, with ownership split across different teams. By 2024, the legacy Python service had a history of reliability and performance issues. Ownership and maintenance of this service had become more cumbersome for all involved teams. Due to this, we decided to move forward into modern and domain-specific Go microservices.

In the second half of 2024, we moved forward with fully migrating the comment model first. Redditors love to share their opinions in comments, so naturally the comment model is our largest and highest write throughput model, making it a compelling candidate for our first migration.
