I've used it a fair bit, though not for a couple of years. Trying to keep this config in source control with multiple devs working on it was impossible. This results in huge graphs of processors with s of boxes with lines between you have to follow.

Made both better and worse by being able to descend and ascend levels in the graph. The complexity that way quickly becomes insane.

I've no doubt you could use it to write, say, an XMPP server if so inclined. Which means you can do a great many things of huge complexity.

Programming tools have developed models for inheritance and composition, abstraction, static analysis, etc. The amount of repeated logic I've seen it's configuration accumulate is beyond anything I've seen from any novice programmer.

I ended up feeling like it could be an OK choice in a very small number of places, but I never got to work on one of those.

The NSA linking together multiple systems with a light touch is possibly one such use case. For most everyone else, I couldn't recommend it. That is sort of the key problem I see with NiFi and equivalents.

The heavy emphasis on graphical UI and visual paradigm sort of implies that its oriented towards non-developers, but problem is that it doesn't make non-developers suddenly expert system architects or developers even if they manage to click through the UI. And many developers probably prefer just defining stuff in code instead of having fancy UIs.

So it sort of falls between these to categories. Of course there is huge spectrum of skill in people, and there are probably plenty of "semi-technical" persons to whom this is perfect match, especially if supported by some more techy people. Doesn't Microsoft Access have a similar interface? It's been a long time since I've used it.

EvanAnderson 5 months ago. The configuration management tooling for SSIS is pretty good and it's amenable to version control better than, it sounds like, NiFi is. SSIS still suffers from the potential "gotchas" the top-level poster mentions.

I haven't used SSIS since about SQL - back then it terrible to use with version control - not only was it a huge blob of XML, it had more xml escaped and shoved into attributes of the main document! Whats more it seemed to re-allocate the GUIDs of the elements every time you opened a diagram, so there were always changes Sounds like it's improved a bit since then.

To me, honestly, this seems more similar to Azure Data Factory. I have no experience with NiFi itself. I don't think it's about whether a graphical tool is performant.

Many programming languages aren't performant either. It's more that graphical tools don't generally serve their stated purpose of making it possible for non-programmers to get things done because it appears that the main skill behind programming is actually problem decomposition and modelling rather than syntax. Additionally, graphical tools tend to have a bunch of problems inherent to them, such as being unable to write comments and harder to store in git and work on collaboratively and only having one single editor, which is usually much buggier than a text editor and compiler.

So: graphical "languages" don't make most things much easier, and make other things much harder. This is where declarative and intention-oriented systems shine. Take something like SQL, where, in the majority of cases, the end-user needs to know next to nothing about algorithmic complexity and can still achieve excellent performance and correct results.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

Technical Archiving or Indexing? Go Punchline! Announcement Craig Release 5.Here are Kubernetes Interview Questions for fresher as well as experienced candidates to get the dream job. Kubernetes is a container management system developed in the Google platform. The purpose of kubernetes is to manage a containerized application in various types of physical, virtual, and cloud environments. Google Kubernetes is a highly flexible container tool to deliver even complex applications, consistently.

Applications run on clusters of hundreds to thousands of individual servers. It defines a single machine in a cluster that can be a virtual machine from a cloud provider or physical machine in the data center. Every machine available in the Kubernetes cluster can substitute other machines.

Kube-scheduler is the default scheduler for Kubernetes. It assigns nodes to newly created pods. They are used for host layers attributes like monitoring network or simple network. Kubernetes is the Linux kernel which is used for distributed systems. It helps you to be abstract the underlying hardware of the nodes servers and offers a consistent interface for applications that consume the shared pool of resources.

It enables the running of more than one process on the master node. Namespaces in Kubernetes are used for dividing cluster resources between users. It helps the environment where more than one user spread projects or teams and provides a scope of resources. It helps you to avoid vendor lock issues as it can use any vendor-specific APIs or services except where Kubernetes provides an abstraction, e.

It will enable applications that need to be released and updated without any downtime. Kubernetes allows you to assure those containerized apps run where and when you want and help you to find resources and tools which you want to work. It is the entry point for all kinds of administrative tasks. There may be more than one master node in the cluster to check for fault tolerance. Scheduler: The scheduler schedules the tasks to the slave node.

It stores the resource usage information for every slave node.

It is responsible for distributing the workload. Etcd: etcd components, store configuration detail, and wright values. It communicates with the most component to receive commands and work. It also manages network rules and port forwarding activity. Kubelet: It gets the configuration of a Pod from the API server and ensures that the described containers are up and running. Docker Container: Docker container runs on each of the worker nodes, which runs the configured pods.

Pods: A pod is a combination of single or multiple containers that logically run together on nodes. It opens a particular port on all nodes and forwards network traffic sent to this port.Apache NiFi provides a large and diverse library of processors for acquiring and transforming data, and a flow registry for versioning these often complex data flows.

B23 uses NiFi across multiple infrastructure and orchestration platforms, including Kubernetes. Our pioneering NiFi engineering work allows us to programmatically provision data flows using a library of pre-existing, best-in-class, data flows that we have developed and honed after many years of operational use.

Thanks to the recent development work on the NiFi-Fn project by Sam Hjelmfelt at Cloudera, there is now a direct path to running NiFi Flows directly on Kubernetes without the need and overhead of an administratively complex NiFi cluster.

The NiFi-Fn project brings to NiFi the ability to execute pre-existing data flows as serverless applications. What this means NiFi users is that flows can now be started on-demand and run to completion with success determined by the successful processing of all flow files sent as inputs to the flow.

An inspiration for our work was the recently open sourced Kubernetes Operator for Apache Spark released by Google. This allows us to create and manage our data flows just like any other resource in Kubernetes. This lets Kubernetes handle the semantics of retry and cleanup while giving the user control over the logic and execution of the flow.

It has been tested locally with docker-for-desktop and in the cloud with Google Kubernetes Engine. We have many ideas about how to improve this new capability and we look forward to working closely with the NiFi community to develop it further. Search for:.

As mentioned in the Comments, work has been done regarding Nifi on Kubernetes, but currently this is not generally available. It is good to know that there will be dataflow offerings where Nifi and Kubernetes meet in some shape or form during the coming year.
