In today's data-driven world, the need for near real-time data extraction, transformation, and loading (ETL) has become a cornerstone of successful data analytics. Businesses increasingly rely on the speed and accuracy of near real-time data to make informed decisions, detect anomalies, and seize new opportunities swiftly. Solving real-time or near-real-time data processing challenges requires a multifaceted strategy combining modern technology, best practices, and skilled personnel.

Near real-time data preparation: Extract, Transform, and Load (ETL) is crucial for several use cases where timely insights are essential for making informed decisions and taking immediate action. Here are the top use cases that require real-time or near-real-time data that I see most frequently:

  • Fraud Detection and Prevention: Near real-time ETL processing is vital for identifying fraudulent activities as they occur. By analyzing transactional data from multiple internal and external sources in near real-time, organizations quickly detect unusual patterns and flag potentially fraudulent transactions, helping to improve customer experience and minimize financial losses.
  • Dynamic Pricing and Revenue Optimization: In industries like e-commerce, travel, and hospitality, businesses should regularly adjust prices for their products and services in response to changing market conditions and demand. Near real-time ETL enables organizations to gather and analyze current interest, availability, and demand data, allowing dynamic pricing decisions that optimize revenue.
  • Supply Chain Optimization: Efficient supply chain management relies on up-to-the-minute data on product availability levels, demand, and shipping logistics. Top-performing businesses process data in near real-time from multiple internal and external resources to provide the most accurate visibility into the supply chain, helping organizations make better proactive decisions to reduce costs and improve efficiency.
  • Customer Experience Enhancement: Businesses in various consumer sectors, including retail, telecommunications, and online services, use near real-time data ETL to analyze customer behavior and feedback. By processing data from websites, mobile apps, and call centers in near real-time, organizations personalize recommendations, address customer issues proactively, and enhance the overall customer experience.

In these use cases, near real-time ETL ensures that organizations ingest, transform, and make the most current data available for analysis as quickly as possible, leading to better data-driven decisions resulting in proactive rather than reactive responses to changing conditions.

Traditional batch-oriented ETL processes do not suffice in delivering timely insights. This blog post will highlight the top challenges businesses face implementing near real-time data ETL and our best practice recommendations.

Near Real-Time ETL Challenges

  • Data Velocity: Near real-time ETL must process high-velocity data streams (i.e., Twitter, sensors) from multiple sources. Managing and timely processing of these data firehoses differs entirely from traditional batch data pipelines. Lydonia Technologies recommends leveraging scalable data streaming platforms like Apache Kafka or AWS Kinesis. These platforms can ingest, buffer, and distribute data processing and storage efficiently, ensuring you can keep up with the data velocity.
  • Latency Reduction: Minimizing latency during ETL processing is paramount for timely insights. Delays during ETL processing hinder decision-making and impact business performance. Lydonia Technologies suggests embracing parallel processing techniques and in-memory databases to reduce latency. For example, Alteryx has recently automated pushdown to cloud database processing. Pushdown processing performs the data transformation process inside the cloud data warehouse (i.e., Snowflake, Databricks, Redshift, BigQuery), removing the need to egress already loaded data and allowing for nearly infinite scalability of processing resources. This approach can significantly improve data processing speed and provide near real-time results.
  • Scalability and Elasticity: Adapting to fluctuating workloads and scaling resources cost-effectively is essential for near real-time data ETL, especially when dealing with unpredictable data surges. Implement auto-scaling mechanisms with cloud-based services for elasticity. Lydonia Technologies encourages organizations to automate resource allocation dynamically based on workload demands, ensuring your ETL system can handle peaks without costly overprovisioning.
  • Data Integration Complexity: Near real-time ETL often involves integrating data from diverse sources, each with its format and schema. Ensuring compatibility and consistency across these sources can be complex. Lydonia Technologies advises using data integration tools and ETL processes to harmonize data from different sources. Additionally, leverage APIs and connectors to facilitate seamless data integration, mainly when dealing with legacy systems. For example, our technology partner, Alteryx, provides pre-built connectors for over 300 commercial data sources. Using pre-built connectors simplifies automating new and maintaining existing data source pipelines.
  • Automating Data Error Handling and Recovery: In a high-velocity environment, errors are inevitable. Ensuring a robust automated error handling and recovery system is vital to prevent data loss and maintain the integrity of data pipelines. Lydonia customers implement comprehensive logging, automated detection, and alerting mechanisms. Automated recovery techniques, such as rolling back transactions, quarantining, repairing, and reprocessing data, can ensure minimal disruption when inevitable exceptions arise.
  • Skill Gap and Expertise: The ever-evolving landscape of technology demands a skilled workforce. Finding professionals well-versed in near real-time data and ETL can be challenging. Lydonia Technologies stresses the value of a knowledgeable crew with the latest skills and expertise. The reality is a culture of Hyperautomation – "automate everything automatable" is necessary to meet modern customer demands while providing the best possible employee experience.


In the realm of near real-time data ETL, challenges abound. Still, with the right strategies and solutions, businesses can harness the power of timely insights to drive their success. Lydonia Technologies has shown that companies can confidently navigate these challenges by addressing near real-time ETL.

As the data landscape evolves, Lydonia Technologies and our technology partners remain committed to helping organizations conquer these challenges, resulting in data-driven leaders consistently outperforming their competition. By staying at the forefront of data technology and best practices, we ensure businesses can make the most of their data portfolio and thrive in today's fast-paced, data-driven world.
