Everything so far ran because you typed it. Apache Airflow runs it on a schedule, retries it, and keeps a record of every run. It doesn't touch the data itself: its tasks talk to Spark through the same Connect server you've been using, so the Airflow image carries only the thin pyspark-client 4.2.0 (the version the Airflow 3.3.2 constraints pin, and the server's) and no JVM. The repo ships two DAGs:

agent-framework
A framework for building, orchestrating and deploying AI agents and multi-agent workflows with support for Python and .NET.
Project mention: Microsoft Agent Framework behind a corporate proxy: the HTTP transport that ignored HTTPS_PROXY | dev.to | 2026-10-06That's what happened to me with the TypeSafe (Jev) connector in Microsoft Agent Framework. The fix was merged by the Microsoft team on October 6, 2026: microsoft/agent-framework#8984.

dstack
A unified orchestration layer for heterogeneous AI compute. It standardizes how to manage compute and run training and inference on GPU clouds, Kubernetes, VMs, or bare-metal clusters.
-
-
Automatic crash detection for your process is built-in our Conductor offering. The library has a default recovery mode when used standalone.
What do you find strange with workflow versioning? Would love to consider improving the semantics. In fact, we started doing it: https://github.com/dbos-inc/dbos-transact-py/pull/598

Project mention: How Failing at Fantasy Baseball Made Me Fix My Cron Jobs with Temporal | dev.to | 2026-05-05
Well, I’d been meaning to fix that setup anyway. This time I did — and instead of patching the script, I tried out Temporal and…it worked embarrassingly well. Retries, backoff, execution history — things I’d normally bolt on manually were just… there. And if the network layer itself was flaky — rate limits, geo blocks — I could just add a proxy as a hardening layer.

pipelex
Build AI methods with your coding agent, then run them anywhere: as an MCP for chatbots, as a webapp for people, or via API for your software.
Project mention: Show HN: Pipelex – declarative language for repeatable AI workflows (MIT) | news.ycombinator.com | 2025-10-28 -
covalent
Pythonic tool for orchestrating machine-learning/high performance/quantum-computing workflows in heterogeneous compute environments. (by AgnostiqHQ)
