27 tracked signals on database.
Databricks Lakebase reimagines Postgres with object storage and WAL for agentic AI workloads
“Agents that interact with a traditional OLTP database often create bottlenecks at the storage layer.”
Microsoft rebranded Data API Builder as 'SQL MCP Server' to enable AI agents to query databases via MCP
“there's no agent that can automatically talk to a database. So you have to create this in between service.”
Microsoft built Azure HorizonDB, a 99.9% Postgres database with separated compute/storage and Rust-built storage, for tier-1 scalability.
“HorizonDB is built on the concept of database as logs and separation of compute and storage, which allows compute and storage to scale independently.”
Microsoft SQL Server adds updatable vector indexes with faster builds and iterative filtering
“we've made it updatable. The original index was not updatable.”
pg_duckdb is a Postgres extension embedding DuckDB's analytical engine to run fast OLAP queries inside Postgres without data movement.
“It's like bringing the capabilities of OLTP and OLAP at one place.”
Microsoft launched HorizonDB public preview and made 345 Postgres 19 commits while advancing AI-enhanced database tooling.
“In Postgres 19, Microsoft made about 345 commits to the upstream project and changed around 64,000 lines of code.”
Microsoft announced Azure HorizonDB, a new Postgres service in public preview at Build.
“what we're trying to do with Horizon DB is really serve a very large market by bringing a bunch of new AI capabilities and developercentric tooling in VS Code”
Databricks Lakebase now autoscales Postgres instances to match workload demand.
A large European bank migrated very large Oracle workloads to Azure Database for PostgreSQL to cut costs.
“the cost becomes a moot point if performance is not met”
Databricks Lakebase introduces Always-On pricing for automatic cost savings on managed databases
Databricks Lakebase introduces branch-based Postgres restores to speed up OLTP recovery at scale
Databricks Lakebase offers cost optimization strategies for managed Postgres workloads
Azure SQL Hyperscale separates compute and storage to scale AI app backends to 128TB
“One of the superpowers of Hyperscale is a concept called named replicas, up to 30 of them.”
Microsoft SQL adds 192 V-core Hyperscale support and agent-aware Terraform API coverage
Postgres 19 enters feature freeze with self-tuning async I/O worker pools as a headline improvement.
“Andres Freund reviewed my patch and he looked at it and said, it seems to work really well, but I have no idea why.”
Microsoft built Azure DocumentDB by open-sourcing its managed MongoDB-compatible, Postgres-backed engine and feeding learnings back into the service.
“we started with a managed service, went back into building an open source engine from the managed service, but then funneled all of our open-source learnings from the project back into the managed service”
VS Code SQL projects now offer offline IntelliSense and real-time schema error detection
“developers are getting AI. And so your database has to continue to change with the rest of your application.”
Azure SQL Database Hyperscale enables SQL Server migration without application rewrites
“Migrating to Hyperscale isn't a full application rewrite.”
Azure SQL Hyperscale is not just for large databases, Microsoft wants developers to start with it by default
“Nowadays, people think it's only for the largest databases. So, I hope one of the things I'm going to dispel today is that myth.”
Azure SQL Hyperscale offers seamless scaling from free tier to 128TB without rebuilding
“All you need to do is when you get to the paid offer, go to Azure SQL database Hyperscale”
A practical guide arguing range-based partitioning is the only good way to partition large Postgres tables.
“If your tables are around 100 gigabytes, that's a good moment to start to think about partitioning.”
Postgres NOTIFY in triggers forces accidental serialization via a global pg_database lock, stalling concurrent commits.
“Postgres treats LISTEN/NOTIFY like a globally serialized queue of notifications”
POSETTE 2026 Livestream 4 previews talks on Postgres partitioning, SQL/PGQ graph queries, logical replication, and PG DuckDB analytics.
“SQL PGQ is the latest addition to SQL standard.”
Postgres uses pg_statistic stats like correlation and most-common-values to decide between sequential and index scans.
“Now you might be tempted to think that something's broken, but it's actually working just fine.”
A developer demonstrates underused PostgreSQL features—range types, generated columns, and exclusion constraints—to solve real application problems more elegantly than standard SQL.
“engineering still needs creativity”
Azure SQL Managed Instance now offers a free 12-month trial tier for cloud testing
