Xata is now on Google Cloud. Spin up an isolated Postgres branch from your production data in 3 seconds, in-region in us-central1 (Iowa). Every coding agent, PR, and CI run gets its own production-like database. No shared staging, no migration.

Very proud that we are be able to sponsor pgBackRest and therefore help with the continuing maintenance of the project. It's rock solid and fast, the properties you want from the backup solution. It's the safety net we offer to all @xata.io customers.

We run 100% vanilla Postgres. No fork, no modifications. A deliberate decision from day one to build a platform around Postgres, with branching at the storage layer instead of inside the database. This means the whole Postgres ecosystem just works with Xata.

Branching gives every engineer and every agent their own Postgres. Now every branch has its own logs. Read, filter, and search them in the console, or match a pattern in one click. Same logs in your terminal with xata branch logs.

Every Xata Postgres branch now has a managed PgBouncer endpoint, in the same memory envelope as the database. Auto-tuned to 0.9 of max_connections. 10,000 client connections per branch. Hibernates with the branch. Append `-pooler` to your branch ID. Writeup: xata.io/blog/a-conne...

Postgres connection pooling per branch | Xata by Noémi Ványi

Every Xata Postgres branch includes a built-in PgBouncer pooler in transaction mode. Tuned for serverless and edge, scales to zero with the branch.

I’ve written a blog post on why and how we built our own distributed storage engine. We’re calling it Xatastor and enables us to scale to a huge number of Postgres instances and branches. It’s based on ZFS and NVMe-oF as key technologies. xata.io/blog/xatasto...

Xatastor: ZFS + NVMe-oF for millions of Postgres instances by Tudor Golubenco

Read the technical details of our new distributed storage system, which is the key to scaling to a huge number of Postgres instances.

Today we're open sourcing the Xata platform, a cloud-native Postgres platform. - Fast copy-on-write branching. - Automatic scale-to-zero. - 100% Vanilla Postgres. We run upstream Postgres, no modifications. - Production grade: HA, failover/switchover, upgrades, PITR, IP filtering, etc.

Xata is now open source. Apache 2.0. Postgres platform with Copy-on-write branching at the storage layer. Copy a TB-sized database in seconds. Inactive copies scale to zero automatically. 100% vanilla Postgres.

Batching is often used to process large volumes of data but a batch size that works in one network setup can perform poorly in another. We applied automatic batch size tuning to Postgres snapshots in pgstream to adapt across different network environments. Check the post 👇 xata.io/blog/postgre...

Optimizing data throughput for Postgres snapshots with batch size auto-tuning by Esther Minano Sanz

Why static batch size configuration breaks down in real world networks and how automatic batch size tuning improves snapshot throughput.

Postgres constraints are the rules that keep your data clean. Types tell you *what* can be stored but constraints enforce *what must be true*. If a row violates a rule, Postgres rejects it. No silent corruption. A few well-chosen constraints prevent entire classes of bugs. xata.io/blog/constra...

What you should know about constraints in PostgreSQL | xata.io by Gulcin Yildirim Jelinek

In this blog, we explore Postgres constraints through the pg_constraint catalog, covering table vs. column constraints, constraint triggers, domains and more.

Can an AI Agent follow the same workflow that human developers can? We explored giving AI agent access to the database branch, a compute sandbox to execute code and instructions to follow a developer workflow (in plain English) and the experiment was a success.

PostgreSQL 18 is here 🎉 🐘 • Async I/O (io_uring/worker), faster reads • More index hits (skip scan, OR) • uuidv7(), virtual generated cols • OAuth2; Ask for Xata access and try PostgreSQL 18.

The summer edition of the London Postgres Meetup is behind us! Thanks to the organisers for a great evening. Chris Ellis gave a sharp talk on UUIDs, and Andrew Farries introduced pgroll, our open-source tool for zero-downtime schema changes. Always a joy to talk Postgres over pints!
