In the ever-evolving landscape of data, the past few years have witnessed a profound transformation. Within a mere span of two years, we’ve generated more data than in the entire history since the inception of the internet. This explosive growth in data creation has left organizations scrambling to find ways to not only manage but also leverage this vast wealth of information for informed decision-making. However, this ambitious endeavor hinges on the foundation of robust and efficient data processing systems. Welcome to the world of Real-Time ETLT, where we delve into how this cutting-edge approach is meeting the insatiable demands of modern data processing.
ETLT (Extract, Transform, Load, Transfer) is the newest added paradigm that could be the next best thing for data processing workflows. Instead of batch and micro-batch processing, businesses are transitioning towards real-time processes and in-time business decisions.
With real-time processing, businesses can take proactive decisions and respond immediately to changing circumstances, with anomaly detection, automation and key trend analysis.
However, real-time processing brings its own set of challenges, and with high data volume, ensuring data accuracy and security becomes a concern.
Challenges for ETLT
- Managing big data
In the era of big data, the amount of data companies generate and process every instance can be overwhelming. If not implemented correctly with the best practices, handling this massive data can be a tough challenge
- Ensuring data robustness and accuracy
Among many aspects, data consistency and reliability are at the core of the data analytics domain. Without it, any insights from the data are not useful, so it is a big concern for data teams. The ETLT process must deliver results while keeping up with data consistency
- Manage data security
This rule applies all across the board when it comes to dealing with data, particularly if it is personal data. Any process of the data pipeline must fulfil the necessary security protocols and ETLT is no different.
While these challenges exist, brilliant minds at work have found solutions to the same too. Data teams and developers have designed reliable processes to help mitigate these issues
Solutions for managing real-time ETLT pipelines
- Leveraging robust streamlining technologies
Modern-day data processing systems are enhancing batch processing frameworks for real-time data. A big step towards achieving this is streaming solutions like Kafka, Flink and micro batching. These out-of-the-box applications have offered a great leap towards the future
- Defining data encryption protocols and security measures
Complex processes like pseudonymization and data encryption are being used to provide an extra layer of security. Data teams follow strict data governance protocols and use a combination of different processes and frameworks to improve security.
- Robust data quality checks and monitoring
Use of quality testing data processing pipelines and implementations is an important part of the software development cycle. However, to address quality issues and data errors, teams implement additional data monitoring frameworks on top of the existing processes.
Extracting Data in Real Time
Although real-time data processing has its challenges, it is the need of the hour and critical for businesses. To achieve this, the industry is standardising the processes and improving methodologies. By using standard formats and data sources for both structured and unstructured data being one of them. Moreover, instead of simple data pooling, Change Data Capture (CDC) and event streaming are becoming the new normal. This improves performance and turnaround time, especially for large data volumes
Transforming and Loading Data in Real Time
Companies across the globe are using industrial solutions and applications to improve their data capabilities. Using data integration pipelines, scalable loading mechanisms and cloud solutions add to more resilient and performant solutions. All of which makes real-time decision-making possible.
Including strong data governance and fault tolerance architecture in the solution development prevents system failures. A blend of all modern and advanced analytical technologies is shaping the landscape for the future of real-time data processing.
While ELT and real-time ETL tools have been the standard for a while, ETLT brings the best of both worlds together. And while it is still new for many industries, it is gaining traction and delivering on its promise. Therefore, making these exciting achievements in AI and machine learning possible.
