Why LLMs Write Incorrect SQL (and What That Means for Your Database)
Most LLM-generated SQL doesn't fail. It runs and returns results, and that's exactly what makes it dangerous. The errors don't surface until they're already in your data. AI-assisted development has made it easier than ever to generate SQL quickly. The problem is that quick and correct are not the same thing, and with databases, the gap between the two has consequences that compound quietly over time. SQL that runs is not the same as SQL that works. LLMs are good at producing SQL that looks ri

A Look Back at 2025
2025 was the year we started noticing things we couldn’t easily explain away. We shipped a lot, but what stuck with us were the patterns we kept seeing in production.

Prior to Readyset, setting up a database cache came at a high cost. To get zippy data access, developers needed to rew

Your application has a read-heavy workloa
