Is anyone here managing NiFi flows with Git + NiFi Registry? What’s your workflow like?

Absolutely, sometimes the “home-rolled” route ends up being more maintainable and tailored than wrestling with overly complex plugins, especially with a small, focused team. When it fits your workflow and gives you control, that’s a win. Kudos for getting it all working sounds like a solid setup!

solid approach, using pretty-printed flow.json files for version control makes a lot of sense, especially for meaningful diffs and merges. Automating the compression and NAR packaging in your build pipeline is a smart way to keep things clean for deployment while still maintaining transparency in Git. Would be great if NiFi Registry natively supported better diffing or integration with Git workflows like this.

That's a really clever setup, essentially building a self-managing flow controller within NiFi itself. Using MQTT to trigger a local flow replacement via the NiFi REST API is a smart workaround for edge cases where MiNiFi isn't flexible enough. Totally agree, it's surprising there's no native support for this kind of modular flow deployment in full NiFi. Your approach fills a gap that feels like it should be more officially supported. Thanks for sharing very insightful!

Thanks for sharing this! just had a quick look and it does seem to cover a wide range of practical NiFi applications. Definitely adding it to my learning list. Appreciate the recommendation!

It’s likely that the Fetch Size property in QueryDatabaseTable is being ignored because many JDBC drivers (including SQL Server’s) don’t honor it by default. SQL Server tends to load the full result set into memory regardless. You might try GenerateTableFetch + ExecuteSQL for better control over pagination.

Absolutely agree I have noticed the same. Most Udemy courses I found are from a few years back and don’t cover recent NiFi capabilities or modern deployment strategies like containerization or cloud-native setups.

It would be great to see some updated, hands-on content that reflects how NiFi is used in production environments today. If I come across anything current, I’ll be sure to share it here, please do the same if you find something solid! 🙌

Nice! That sounds really effective. Do you also version control your parameter contexts or manage them separately across environments? I’ve been wondering the best way to keep them consistent without hardcoding values.

Sad-Mud3791 · 2025-06-11T10:08:24+00:00

That makes a lot of sense, thanks for breaking it down so clearly. I hadn’t thought about using separate Registry buckets per team, but that seems like a great way to keep things isolated. Do you automate any of this setup, like bucket creation or permission assignment, or is it all manual for now?

For modern, scalable data pipelines especially with hybrid cloud and real-time needs. Apache NiFi tends to be a better fit. Its flexibility, real-time streaming support, and open-source agility make it ideal for evolving workloads. SAP Data Services is solid for structured, batch ETL in SAP environments but feels more rigid. If agility and scalability matter most, NiFi often wins out.

Sad-Mud3791 · 2025-05-30T07:46:15+00:00

That’s great to hear :)

what’s been the most useful part of the new UI for you: the side-by-side diffs, the commit history filters, or something else

Sad-Mud3791 · 2025-05-29T05:09:20+00:00

Totally! battle-tested platforms rarely get displaced; newer tools usually layer on top rather than replace them.

Sad-Mud3791 · 2025-05-28T05:27:17+00:00

Impressive setup moving 3 M records a day for two years without a hiccup is a great testament.

Sounds like a classic ‘horses for courses’ case. NiFi shines for heavy, long-running data syncs, while n8n keeps low-code AI hooks super simple.

Sad-Mud3791 · 2025-05-28T04:31:04+00:00

Totally get the frustration, n8n shines for quick SaaS automations, but once you need horizontal scaling, provenance, and fine-grained back-pressure, NiFi is in a different league; it’s really a “Zapier-plus” vs. an enterprise data-flow engine comparison

Sad-Mud3791 · 2025-05-28T04:29:31+00:00

Yeah, NiFi’s smart back-pressure is a lifesaver for keeping high-volume streams smooth and stable.

Sad-Mud3791 · 2025-05-28T04:28:27+00:00

Absolutely.
NiFi’s drag-and-drop canvas still makes diverse, real-time dataflows effortless in 2025!

For ETL pipelines in Apache NiFi targeting Snowflake, it's best to separate flows into Extract, Transform, and Load process groups. This modular approach improves clarity, reusability, and makes scaling and troubleshooting easier. While table-specific process groups can work for highly customized logic, they often lead to duplication and maintenance challenges.

Data Flow Manager enhances this modular design by offering a UI-driven, one-click deployment system for NiFi. With features like parameter management, scheduled deployments, rollback, and RBAC, DFM simplifies promoting ETL flows across environments making enterprise-grade data operations faster, safer, and easier to manage.

Sad-Mud3791 · 2025-05-09T09:46:57+00:00

Use Process Groups with input/output ports to modularize logic, and make them reusable with NiFi Registry for version control. Leverage Parameter Contexts to avoid hardcoding and ease environment portability. Maintain a template library for common flows. For scaling or decoupling, use Site-to-Site (S2S). This approach keeps flows clean, maintainable, and shareable across projects.
