Move away from batch ETL with next-gen Change Data Capture

As data volumes continue to grow, enterprises are constantly looking for ways to reduce processing time and expedite insight extraction. However, with traditional databases and batch ETL processes, performing analytical queries on huge volumes of data is time-consuming, complex, and cost intensive.

Change Data Capture helps expedite data analysis and integration by providing the flexibility to process only the new data through a smart data architecture, thus incrementally computing updates without modifying or slowing down source systems. This enables enterprises to reduce overheads, improve hardware lifetime, and ensure timely data processing without facing the limitations of batch processing.

That probably sounds like an oversimplified solution to a very complex problem. So, let’s break it down.

Data extraction is integral to data warehousing and data is often extracted on a scheduled basis in bulk and transported to the data warehouse. Typically, all the data in the data warehouse is refreshed with data extracted from the source system. However, an entire refresh involves the extraction and transportation of huge volumes of data and is very expensive in both resources and time. This is where Change Data Capture plays an important role by replicating data in a big data lake with incremental computing updates without modifying or slowing down source systems.

This makes it easy to structure and organize change data from enterprise databases to provide instant insights. Gathr allows you to ingest, blend, and process high velocity big data streams as they arrive, run machine learning models, and train and refresh models in real-time or in batch mode. There are two parts to a Change Data Capture solution with Gathr :

ETL vs ELT: Which data integration practice is right for you

ETL and ELT are common data integration practices that are extensively used in data science and business intelligence. While leading enterprises use both approaches, you might be wondering what is the difference between ETL and ELT?

Find out which data integration practice is right for you in this head-to-head ETL vs ELT comparison.

These 3 Trends will shape the data and analytics landscape in 2022

In 2021, we witnessed an explosion in cloud adoption as enterprises continued to focus on digital transformation in response to the global pandemic. Many companies tested the waters by moving data, analytics, and business use cases to the cloud for the first time. Both cloud adoption and migration will continue to gain momentum in 2022 across industries, with DataOps, 5G, and edge analytics playing key roles in the digital transformation journey. Here’s what we can look forward to in 2022.

Self-service ingestion: The key to creating a unified, scalable, cloud data lake

Enterprises are increasingly leveraging cloud-based data lakes to run large-scale analytics workloads and tap data-driven insights for better decision making. Cloud-based data lakes offer unmatched elasticity and scalability, enabling businesses to save costs and improve time-to-market.

The first step in creating a data lake on a cloud platform is ingestion, yet this is often given low priority when an enterprise enhances its technology. It’s only when the number of data feeds from multiple sources starts increasing exponentially that IT teams hit the panic button as they realize they are unable to maintain and manage the input.

Self-service ingestion can help enterprises overcome these challenges and unlock the full potential of their data lakes on the cloud. Here are a few of the benefits.

Why modernizing ETL is imperative for massive scale, real-time data processing

During the past few years, a sea change occurred in the way enterprises acquire, process, and consume data. The exponential surge in the number of data sources and customer interactions fueled a major paradigm shift, with real-time stream processing and cloud technologies emerging as the backbone of intelligent decision making. This is driving businesses to re-look at traditional extract, transform, and load (ETL) platforms used to integrate data from multiple sources into a single repository. This article explores the need for ETL modernization and provides insights for evaluating ETL platforms and ensuring a seamless modernization journey.
