Data Pipelines
Enter the modern data stack: a technology stack designed and equipped with cutting-edge tools and services to ingest, store, and process data. No longer are we using data only to drive business decisions; we are entering a new era where cloud-based systems and tools are at the heart of data processing and analytics. Data-centric tools and techniques — like warehouses and lakes, ETL/ELT, observability, and real-time analytics — are democratizing the data we collect. The proliferation of and growing emphasis on data democratization results in increased and nuanced ways in which data platforms can be used. And of course, by extension, they also empower users to make data-driven decisions with confidence.In our 2023 Data Pipelines Trend Report, we further explore these shifts and improved capabilities, featuring findings from DZone-original research and expert articles written by practitioners from the DZone Community. Our contributors cover hand-picked topics like data-driven design and architecture, data observability, and data integration models and techniques.
Development at Scale
As organizations’ needs and requirements evolve, it’s critical for development to meet these demands at scale. The various realms in which mobile, web, and low-code applications are built continue to fluctuate. This Trend Report will further explore these development trends and how they relate to scalability within organizations, highlighting application challenges, code, and more.
Enterprise AI
In recent years, artificial intelligence has become less of a buzzword and more of an adopted process across the enterprise. With that, there is a growing need to increase operational efficiency as customer demands arise. AI platforms have become increasingly more sophisticated, and there has become the need to establish guidelines and ownership.In DZone's 2022 Enterprise AI Trend Report, we explore MLOps, explainability, and how to select the best AI platform for your business. We also share a tutorial on how to create a machine learning service using Spring Boot, and how to deploy AI with an event-driven platform. The goal of this Trend Report is to better inform the developer audience on practical tools and design paradigms, new technologies, and the overall operational impact of AI within the business.This is a technology space that's constantly shifting and evolving. As part of our December 2022 re-launch, we've added new articles pertaining to knowledge graphs, a solutions directory for popular AI tools, and more.
Machine Learning
Industry leaders discuss the latest trends in machine learning. We dive into using machine learning with microserivces, deploying machine learning models in real-life applications, and where the field is going over the next 12 months.

Put them into 2 docker nodes. Are you using https://hub.docker.com/r/apache/nifi-registry Is configuration right? It has to store data.https://nifi.apache.org/docs/nifi-registry-docs/html/getting-started.html

Install Java 8
Install NiFi https://nifi.apache.org/download.html
Install Kafka https://kafka.apache.org/downloads
Or get a linux box or big VM

we don't have one to list all topics. you could call kafka-topics.sh to get the list or make an API call

good point, this was a follow up to the other article, should have had a review. sorry.

Josh Long is great, when I worked at Pivotal I got a few articles in the Spring Weekly list.

Spring for Hadoop hasn't been updated in forever. It is stuck on HDP 2.2 and we are on HDP 2.6. Spring Data JDBC and Spring Data Repositories make a lot of sense. I should do that, I'll do an update when I get the chance. Maybe add Java 9 and some other goodies. Thanks for the suggestions. If you want to fork the github repo, please do!

You need to install the OpenNLP models and reference that in the processor properties. Also OpenNLP misses a lot of names and locations. Accuracy is kind of hit or miss. https://github.com/tspannhw/nifi-nlp-processor https://community.hortonworks.com/articles/163776/parsing-any-document-with-apache-nifi-15-with-apac.html

Jean-Paul,
There's another open source registry that integrates with Kafka and other systems extremely well and has a great REST API and UI:
https://github.com/hortonworks/registry
It has versioning and is moving to adding protocol buffers and going into Apache.
Have you tried that one?

NiFi can run on a cluster of servers to distribute the load. NiFi generally supports 50 megabytes a second per node

i have seen a lot of messy code. You bring it into IntelliJ / Eclipse and format the code, hide the bad comments and run some static code analysis tools. Java is nice for that.

Good catch. I like your second idea better though.
