Kafka Event Streaming AI and Automation

Aggregated on: 2023-10-17 18:32:04

Apache Kafka has emerged as a clear leader in corporate architecture for moving from data at rest (DB transactions) to event streaming. There are many presentations that explain how Kafka works and how to scale this technology stack (either on-premise or cloud). Building a microservice using ChatGPT to consume messages and enrich, transform, and persist is the next phase of this project. In this example, we will be consuming input from an IoT device (RaspberryPi) which sends a JSON temperature reading every few seconds. Consume a Message As each Kafka event message is produced (and logged), a Kafka microservice consumer is ready to handle each message. I asked ChatGPT to generate some Python code, and it gave me the basics to poll and read from the named "topic." What I got was a pretty good start to consume a topic, key, and JSON payload. The ChatGPT created code to persist this to a database using SQLAlchemy. I then wanted to transform the JSON payload and use API Logic Server (ALS - an open source project on GitHub) rules to unwarp the JSON, validate, calculate, and produce a new set of message payloads based on the source temperature outside a given range.

Understanding Supervisor in Apache Druid

Aggregated on: 2023-10-16 15:32:03

Although both Apache Druid and Apache Kafka are potent open-source data processing tools, they have diverse uses. While Druid is a high-performance, column-store, real-time analytical database, Kafka is a distributed platform for event streaming. However, they can work together in a typical data pipeline scenario where Kafka is used as a messaging system to ingest and store data/events, and Druid is used to perform real-time analytics on that data. In short, indexing is the process of loading data in Druid, and Druid reads the data from a streaming source system like Kafka and eventually stores it in data files called segments. Druid includes an Apache Kafka Indexing Service that enables Druid to accept data streams from Apache Kafka, analyze the data in real time, and index the data for querying and analysis. A supervisor is a built-in part of Druid, making it easier to ingest, analyze, and monitor data in real-time. The data ingestion lifecycle is managed by druid supervisors. They handle jobs like reading information from a streaming source (like Kafka topics), indexing it into Druid segments, and keeping track of the ingestion procedure. The data ingestion for Kafka streaming ingestion is configured by the supervisor's specification. A JSON specification (often referred to as the supervisor spec) that specifies how the supervisor should consume data from Kafka and how it should process and index that data into Druid must be provided when configuring an Apache Kafka supervisor. Kafka indexing tasks read events using Kafka’s own partition and offset mechanism to guarantee exact-once ingestion. The Kafka supervisor in Druid reads the data in real time from the mentioned topic name and converts them into Druid events based on the submitted supervisor spec. The supervisor applies any necessary transformations or aggregations on the data before indexing it into Druid segments. These segments are essentially Druid’s way of storing and organizing data for efficient querying.

Aggregated on: 2023-10-13 20:02:01

The abstract of this study has established trust is a crucial change for developers, and it develops trust among developers working at the different sites that facilitate team collaborations when discussing the development of distributed software. The existing research focused on how effectively to spread and build trust in not the presence of face-to-face and direct communications that overlooked the effects of trust propensity, which means traits of different personalities representing an individual disposition to perceive another as trustworthy. The preliminary quantitative analysis has been presented in this study to analyze how the trust propensity affects the collaboration success in the different distributed projects in software engineering projects. Here, the success is mainly represented through the request of pull that codes contribute, and changes are successfully merged to the repository projects. 1. Introduction In global software engineering, trust is considered the critical factor affecting software engineering success globally. However, decreased trust in software engineering has been reported to:

Aggregated on: 2023-10-13 20:02:01

Our industry is in the early days of an explosion in software using LLMs, as well as (separately, but relatedly) a revolution in how engineers write and run code, thanks to generative AI. Many software engineers are encountering LLMs for the very first time, while many ML engineers are being exposed directly to production systems for the very first time. Both types of engineers are finding themselves plunged into a disorienting new world — one where a particular flavor of production problem they may have encountered occasionally in their careers is now front and center.

When Software Development Goes Remote: The Crucial Role of Data Management

Aggregated on: 2023-10-13 19:47:01

Remote work is no longer a trend but a mainstream model for many businesses, especially in the software development industry. While remote development has its advantages — talent acquisition from a global pool, reduced overheads, flexibility — it introduces a new set of challenges in data management. The intricacies of managing code repositories, user data, configurations, and even machine learning models across a distributed team can be a daunting task. This article aims to explore the strategies that remote development teams can employ for effective data management. The Data Dilemma in Remote Software Development In a conventional office setting, the infrastructure for data storage, access, and security is usually centralized. But when a software development team is scattered across different time zones, the story changes. Version control is challenging, real-time collaboration on code bases or databases becomes tricky, and data security takes on a whole new level of complexity.
