DBOS Java – Postgres-Backed Durable Workflows

In plain words

DBOS Java is an open-source library that enables developers to build long-running workflows in Java that can survive failures and crashes without losing state. It checkpoints each step of execution to a Postgres database, allowing programs to resume from their exact stopping point after restarts or errors. The tool is designed for applications like AI agents, payment processing, and data synchronization that take extended periods to complete, eliminating the need for manual retry logic and ad-hoc state management.

DBOS provides lightweight durable workflows built on top of Postgres. Essentially, it helps you write long-lived, reliable code that can survive crashes, restarts, and failures without losing state or duplicating work. As your workflows run, DBOS checkpoints each step they take in a Postgres database. When a process stops (fails, intentionally suspends, or a machine dies), your program can recover from those checkpoints to restore its exact state and continue from where it left off, as if nothing happened. In practice, this makes it easier to build reliable systems for use cases like AI agents, data synchronization, payments, or anything that takes minutes, days, or weeks to complete.…from github.com

  DBOS TypeScript – Lightweight Durable Execution Built on Postgres2025 · github.com · ▲77

  Hi HN - Peter from DBOS here with my co-founder Qian (qianl_cs) Today we want to share our TypeScript library for lightweight durable execution. We’ve been working on it since last year and recently released v2.0 with a ton of new features and major API overhaul. https://github.com/dbos-inc/dbos-transact-ts Durable execution means persisting the execution state of your program while it runs, so if it is ever interrupted or crashes, it automatically resumes from where it left off. Durable execution is useful for a lot of things: - Orchestrating long-running or…

  Hi HN - I’m Peter, here with Max (hmaxdml), and we’re building DBOS Go, an open-source Go library for durable workflows, backed by Postgres. https://github.com/dbos-inc/dbos-transact-golang DBOS workflows make your programs durable by automatically checkpointing their state to Postgres. If your program crashes or fails, all workflows seamlessly resume from their last completed step when your program restarts. This durability makes workflows useful for solving many different problems, including: - Operating an AI agent, or anything that connects to an unreliable or…

  DBOS transact – Ultra-lightweight durable execution in Python2024 · github.com · ▲89

  Hi HN - DBOS CEO here with the co-founders of DBOS, Peter (KraftyOne) and Qian (qianli_cs). The company started as a research project of Stanford and MIT, and Peter and Qian were advised by Mike Stonebreaker, the creator of Postgres, and Matei Zaharia, the creator of Spark. They believe so strongly in reliable, serverless compute that they started a company (with Mike) to bring it to the world! Today we want to share our brand new Python library providing ultra-lightweight durable execution. https://github.com/dbos-inc/dbos-transact-py Durable execution means your program…

  Lightweight Durable Workflows Built on Postgres2025 · github.com · ▲5

  Hi HN! This is Qian here with Peter (KraftyOne) and Jeremy (jedberg). We’re building DBOS, an open-source, lightweight durable workflows library that you can add to Python apps in just a few lines of code. It’s comparable to popular open-source workflow and queue libraries like Airflow and Celery, but more lightweight with a greater focus on reliability and automatically recovering from failures. Our goal in building DBOS is to make workflows lightweight and flexible so you can add them to your existing apps with minimal work. Everything you need to run durable workflows and queues is…

  DBOS – Transactional Serverless for TypeScript Apps2024 · github.com · ▲43

  Hello HN! We’re excited to show you DBOS, a transactional serverless SDK and platform that makes it easy to write fault-tolerant, observable, and scalable TypeScript applications. We’re a startup commercializing research we did at Stanford and MIT. (https://dbos-project.github.io/). The main idea behind DBOS is to store EVERYTHING about your application in the database. This gives you some unique features: * Reliable execution – Your program’s execution state is stored in the database, so if it’s ever interrupted, it automatically resumes from where it left off without…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
