This article draws on a Dagster Hybrid deployment on Kubernetes and Azure at a very large enterprise. It covers the work outside the Helm chart: workload ownership, isolation, networking, identity, sizing, and capacity.
Define the outcome, not the orchestration. Declarative Automation lets you express your desired asset state while Dagster continuously handles the work needed to achieve it.
We’re consolidating a decade of legacy systems into Snowflake, which leaves us with over a million columns that all need to be classified and tagged for data governance. I built the system that does it: a tiered classification engine, a human-in-the-loop override workflow, and the orchestration that ties them together. This is the engineering story, the challenges that made it interesting, and where Dagster fits as the orchestration layer. Built solo, to production, in nine days.
Some of the most interesting Dagster projects come from the community. This post highlights creative community-built applications.
A complete guide with all the insights, tips, and some predictions for the data platform engineer, just like an Almanack provides, with practical information for daily life.
Mature orchestration environments often work operationally while still leaving critical data dependencies implicit. This post introduces the Orchestration Maturity Model, explains the architectural ceiling of job-centric systems, and shows how Dagster’s asset-aware approach helps teams reason about freshness, lineage, quality, and self-service at enterprise scale.

Text-to-analytics promises self-service access to data, but adoption depends on usability, governance, and trust. In this guest post, Brooklyn Data explains how it evaluated Compass, deployed it on top of Snowflake, and enabled teams to answer operational questions directly in Slack while maintaining centralized governance and business context.
Snowflake increasingly handles transformation and data freshness internally through features like Dynamic Tables and Cortex. Dagster complements Snowflake by providing orchestration, lineage, automation, and cost visibility across your broader data platform from SQL-defined assets to downstream automation and Snowflake query attribution.
We adopted Astral’s new Python type checker, ty, to speed up type checking in the Dagster monorepo. The performance gains were dramatic, but the bigger surprise was that ty caught real runtime bugs Pyright missed. Here’s what we learned migrating a large Python codebase incrementally to ty.

The Dagster Terraform provider lets platform teams manage deployments, access controls, alerting, and more as code. Define entire environments declaratively, review changes through pull requests, and integrate Dagster into your existing infrastructure workflows.
AI agents that only understand business definitions without knowing whether the underlying pipeline actually succeeded are confidently wrong and operational context from the orchestrator is the missing piece.
Once your pipelines span multiple Databricks workspaces, you're no longer orchestrating a single system you're coordinating a distributed one.

How we configure Copybara for bi-directional syncing to enable a hub-and-spoke model for Git repositories
AI has made contributing to open source easier but reviewing contributions is still hard. At Dagster, we’re improving the contributor experience with smarter review tooling, clearer guidelines, and a focus on contributions that are easier to evaluate, merge, and maintain.
DataOps is about building a system that provides visibility into what's happening and control over how it behaves
Standardizing on Databricks is a smart strategic move, but consolidation alone does not create a working operating model across teams, tools, and downstream systems. By pairing Databricks and Unity Catalog with Dagster, enterprises can add the coordination layer needed for dependency visibility, end-to-end lineage, and faster, more confident delivery at scale.
AI coding agents are changing how data engineers work. This Dagster University course shows how to build a production-ready ELT pipeline from prompts while learning practical patterns for reliable AI-assisted development.

Detection isn't the bottleneck anymore. Understanding is. Compass closes the loop by turning Dagster operational data into a conversation.
When agents write tests, intent matters as much as correctness. By defining clear testing levels, preferred patterns, and explicit anti-patterns, we give agents the structure they need to produce fast, reliable Pytest suites that scale with automation.
Snowflake handles AI compute while Dagster handles orchestration, observability, and the operational patterns that turn AI experiments into reliable production pipelines.
Compass now connects directly to your go-to-market tools, letting you ask questions about pipeline, ad spend, and sales conversations in Slack without exporting CSVs or waiting on the data team.
Modern LLMs generate patterns, not principles. Dignified Python gives agents the intent they lack, ensuring code is explicit, consistent, and engineered with care. Here are ten rules from our Claude prompt.
Benchmarks measure outcomes, not behavior. By letting AI models play chess in repeatable tournaments, we can observe how they handle risk, repetition, and long-term objectives, revealing patterns that static evals hide.
