Deploying a WildFly 30.0.1.Final Cluster Using Ansible

Aggregated on: 2024-02-07 00:47:04

In this brief demonstration, we’ll set up and run three instances of WildFly on the same machine (localhost). Together they will form a cluster. It’s a rather classic setup, where the appservers need to synchronize the content of their application’s session to ensure failover if one of the instances fails. This configuration guarantees that, if one instance fails while processing a request, another one can pick up the work without any data loss. Note that we’ll use a multicast to discover the members of the cluster and ensure that the cluster’s formation is fully automated and dynamic. Install Ansible and Its Collection for WildFly On a Linux system using a package manager, installing Ansible is pretty straightforward:

A Look at Intelligent Document Processing and E-Invoicing

Aggregated on: 2024-02-06 20:32:04

In the "bygone era," invoices were traditionally dispatched in paper format and painstakingly transcribed into the recipient's ERP system facilitating subsequent data processing. As indicated by Brendan Foley, among others, a significant proportion—around 80 to 90 percent—of data from documents like invoices and emails continues to be manually extracted (2019). However, there has been a notable shift in recent years towards the exclusively digital transmission of documents such as business invoices, accompanied by automated data extraction processes. Why should a company (or its managers) embrace this shift? The rationale is clear: to conserve resources (e.g., reducing paper usage) and streamline workflow efficiency (e.g., eliminating manual data entry).

How to Create — and Configure — Apache Kafka Consumers

Aggregated on: 2024-02-06 20:32:04

Apache Kafka’s real-time data processing relies on Kafka consumers (more background here) that read messages within its infrastructure. Producers publish messages to Kafka topics, and consumers — often part of a consumer group — subscribe to these topics for real-time message reception. A consumer tracks its position in the queue using an offset. To configure a consumer, developers create one with the appropriate group ID, prior offset, and details. They then implement a loop for the consumer to process arriving messages efficiently. It’s an important understanding for any organization using Kafka in its 100% open-source, enterprise-ready version — and here’s what to know.

Return To Office Insanity

Aggregated on: 2024-02-06 16:02:04

March 2020. We anxiously watched COVID spread, first through Asia and then Europe before it really impacted the United States. In the second week in March, retail businesses started closing and office workers were instructed to work virtually from home. "Just a couple of weeks, maybe a month," we were told. And now, four years hence, I continue to work full-time from home and don’t expect to change: my employer has stated that in-office or remote work is the employee’s, not the employer’s choice. Cool. “MDI Siemens Cube farm” by babak_bagheri is licensed under CC BY-SA 2.0 Truthfully, my employer is not in a position to force RTO, even scheduled hybrid, as many employees relocated away from headquarters, often leaving the state. Employees have been hired remotely, both before and since the pandemic started. Technically I am a Minnesota – Remote employee even though I am less than ten miles from headquarters. To force in-office work would be hypercritical, though they continue to try and encourage more attendance.

Far Memory Unleashed: What Is Far Memory?

Aggregated on: 2024-02-06 15:32:04

In-memory databases, which offer super fast transaction processing capabilities for OLTP systems and key-value store DBs, are gaining popularity. Some examples of well-known in-memory databases are SAP HANA, VoltDB, Oracle TimesTen, MSSQL In-Memory OLTP, and Memcached. Some less-known ones are GridGain, Couchbase, and Hazlecast. The demand for DRAM has skyrocketed due to the use of in-memory databases for SAP S/4 HANA, big data, generative AI, and data lakes. One of the main challenges in large computer clusters is the limited availability of main memory. For instance, the maximum DRAM for SAP HANA on AWS is 24TB, which costs 63000 USD per month or about 750000 USD per year. On-premises, the maximum DRAM is often 12–18TB. Moore’s law, which states that the number of transistors in an IC doubles every two years, is no longer valid. This means that main memory is becoming more and more of a bottleneck for in-memory databases. A potential solution was Intel’s Optane memory, a non-volatile memory that had similar performance to DRAM at a lower cost, by enabling load/store access at a cache block granularity. However, Intel discontinued Optane, ending its effort to create and market a memory tier that was slightly slower than RAM but had the advantages of persistence and high IOPS.

Are Your ELT Tools Ready for Medallion Data Architecture?

Aggregated on: 2024-02-06 15:32:04

As the world takes a multi-layered approach to data storage, there is a shift in how organizations transform data. It has driven businesses to integrate extract, load, and transform (ELT) tools with Medallion architecture. This trend reshapes how data is ingested and transformed across lines of business as well as by departmental users, data analysts, and C-level executives. Applying rigid data transformation rules and making data available for your teams through a data warehouse may not fully address your business's evolving and exploratory data integration needs. Depending on the volume of data your organization produces and the rate at which it's generated, processing data without knowing the consumption patterns could prove to be costly. Case-based data transformation could be more economically viable as more ad-hoc queries and analyses pop up every day. That doesn't mean you store the data in raw form. Instead, it's necessary to add several layers of transformations, enrichments, and business rules to optimize cost and performance.

Top 5 Reasons Why Your Redis Instance Might Fail

Aggregated on: 2024-02-05 23:47:04

If you’ve implemented a cache, message broker, or any other data use case that prioritizes speed, chances are you’ve used Redis. Redis has been the most popular in-memory data store for the past decade and for good reason; it’s built to handle these types of use cases. However, if you are operating a Redis instance, you should be aware of the most common points of failure, most of which are a result of its single-threaded design. If your Redis instance completely fails, or just becomes temporarily unavailable, data loss is likely to occur, as new data can’t be written during these periods. If you're using Redis as a cache, the result will be poor user performance and potentially a temporary outage. However, if you’re using Redis as a primary datastore, then you could suffer partial data loss. Even worse, you could end up losing your entire dataset if the Redis issue affects its ability to take proper snapshots, or if the snapshots get corrupted.

Next Generation Front-End Tooling: Vite

Aggregated on: 2024-02-05 16:47:03

In this article, we will look at Vite core features, basic setup, styling with Vite, Vite working with TypeScript and frameworks, working with static assets and images, building libraries, and server integration. Why Vite? Problems with traditional tools: Older build tools (grunt, gulp, webpack, etc.) require bundling, which becomes increasingly inefficient as the scale of a project grows. This leads to slow server start times and updates. Slow server start: Vite improves development server start time by categorizing modules into “dependencies” and “source code.” Dependencies are pre-bundled using esbuild, which is faster than JavaScript-based bundlers, while source code is served over native ESM, optimizing loading times. Slow updates: Vite makes Hot Module Replacement (HMR) faster and more efficient by only invalidating the necessary chain of modules when a file is edited. Why bundle for production: Despite the advancements, bundling is still necessary for optimal performance in production. Vite offers a pre-configured build command that includes performance optimizations. Bundler choice: Vite uses Rollup for its flexibility, although esbuild offers speed. The possibility of incorporating esbuild in the future isn’t ruled out. Vite Core Features Vite is a build tool and development server that is designed to make web development, particularly for modern JavaScript applications, faster and more efficient. It was created with the goal of improving the developer experience by leveraging native ES modules (ESM) in modern browsers and adopting a new, innovative approach to development and bundling.

Aggregated on: 2024-02-05 15:02:03

Data lineage is the tracking and visualization of the flow and transformation of data as it moves through various stages of a data pipeline or system. In simpler terms, it provides a detailed record of the origins, movements, transformations, and destinations of data within an organization's data infrastructure. This information helps to create a clear and transparent map of how data is sourced, processed, and utilized across different components of a data ecosystem. Data lineage allows developers to comprehend the journey of data from its source to its final destination. This understanding is crucial for designing, optimizing, and troubleshooting data pipelines. When issues arise in a data pipeline, having a detailed data lineage enables developers to quickly identify the root cause of problems. It facilitates efficient debugging and troubleshooting by providing insights into the sequence of transformations and actions performed on the data. Data lineage helps maintain data quality by enabling developers to trace any anomalies or discrepancies back to their source. It ensures that data transformations are executed correctly and that any inconsistencies can be easily traced and rectified.

Building a Simple gRPC Service in Go

Aggregated on: 2024-02-05 14:47:03

Client-server communication is a fundamental part of modern software architecture. Clients (on various platforms — web, mobile, desktop, and even IoT devices) request functionality (data and views) that servers compute, generate, and serve. There have been several paradigms facilitating this: REST/Http, SOAP, XML-RPC, and others. gRPC is a modern, open source, and highly performant remote procedure call (RPC) framework developed by Google enabling efficient communication in distributed systems. gRPC also uses an interface definition language (IDL) — protobuf — to define services, define methods, and messages as well as serializing structure data between servers and clients. Protobuf as a data serialization format is powerful and efficient — especially compared to text-based formats (like JSON). This makes a great choice for applications that require high performance and scalability.
