How Discord Automates ScyllaDB Clusters at Scale

You've been asked to stand up a brand-new database cluster, meaning a whole day of configuring dozens of nodes, validating replication, wiring up dual-write pipelines… what if this whole ordeal took less than two hours? This is how we got ourselves into this exact mess, and how we made our way out of it.

This means that we need to have ways of sharing common build logic across these repositories. On the JVM Ecosystem team within Java Platform, we build tooling such as the Nebula suite of Gradle plugins to provide standard ways to build projects, keep dependencies up-to-date, and publish artifacts reliably across the Java ecosystem. Our mission also entails pro...

Shaun Thomas: No Compiler Required: Writing SQL-Only Postgres Extensions

Recently at Postgres Conference 2026 in San Jose, I presented a talk called Let's Build a Postgres Extension! Since that entire presentation was primarily focused on writing a C extension while exploring the Postgres source code, I only mentioned pure SQL extensions as an aside. But what's more likely in the Postgres community in general: C devs, or people who know SQL?It turns out that you can do a lot with functions, triggers, views, tables, and various other Postgres-native capabilities....

QBE – Compiler Back End

Are declarative JSON-based schema migrations actually the next step or just hype? Is anyone actually using declarative approaches?

I’ve been exploring a different approach to database migrations where the schema and relationships are defined declaratively in JSON instead of writing imperative SQL migration files manually. The interesting part is that the system can infer diffs, apply changes, track relationships, and potentially keep backend/frontend data contracts more aligned automatically. Honestly, not sure if this is genuinely helpful or if I'm just tired of debugging migration scripts at weird hours. Do you think...
