MySQL

Migrating Etsy’s database sharding to Vitess

Etsy has maintained a sharded MySQL architecture since around 2010. This database cluster contains most of Etsy’s online data and is made up of ~1,000 tables distributed across ~1,000 shards. Over the last 16 years, it has grown significantly: combined, these tables have over 425 TB of data and receive roughly 1.7 million requests per second. Etsy engineers access our MySQL data through a proprietary object-relational mapping (ORM). The ORM has a corresponding model for each MySQL table. W...

Making Ads Count: Using MMoE and Auxiliary Tasks to Better Connect Buyers & Sellers

When buyers search on Etsy, they need to quickly and easily find the perfect item. At the same time, sellers need to be confident their unique products are being seen by the right customers. Our Ads Search ranking model, which is built on a multitask learning foundation, is the critical link in this connection. Recently, we identified an opportunity to drive more meaningful buyer engagement by enhancing our model’s ability to predict purchase intent. We achieved this via a dual-pronged impr...

Shaping Product Understanding with Contrastive Reinforcement Learning

Etsy’s marketplace is defined by the creativity and craftsmanship of our sellers and the hundreds of millions of highly diverse products they offer. You can find silversmiths who cold-forge recycled sterling silver, weavers who dye raw fleece with indigo and black walnut, and ceramicists who throw stoneware on a kick wheel. These details define each product and often determine whether it matches a buyer’s taste, style, and interests. Sometimes buyers know exactly what they want, searching...

How to Build Reliable AI Agents: 5 Engineering Patterns from a Production System

By Tuhin Kanti Sharma and Chirag Ramesh Hegde. If you’ve built an AI agent that works perfectly in demos but becomes unpredictable in production, you’ve probably already discovered that reliability is much harder than capability. We ran into that problem while trying to build an agent to automate capacity optimization worth millions of dollars in […] The post How to Build Reliable AI Agents: 5 Engineering Patterns from a Production System appeared first on Salesforce Engineering Blog.

Christoph Berg: PGConf.dev 2026 in Vancouver

The old Postgres Conferences always sounded interesting, but the conference being in Ottawa in Canada and me being in Europe, I've always dismissed them as "too far away" and never bothered going. Then the organizing team changed and the conference moved to Vancouver for 2024. That's even further away. 2025 in Montreal was a bit closer again, but… At the October 2025 PGConf.EU conference in Riga, everyone was again excited about the upcoming PGConf.dev 2026 conference.
