into smaller chunks to optimize memory usage and processing speed.\n🚀Leverage parallel processing to utilize multiple CPU cores for faster operations.\n🔄Adopt incremental data loads to process only new or modified records, saving resources.\n📊Optimize queries by indexing, filtering unnecessary columns, and using efficient joins.\n🔐Use compression techniques to reduce data transfer times and storage costs.\n🔄Schedule ETL processes during off-peak hours to maximize system performance.\n🛠Monitor and adjust ETL performance metrics regularly to identify bottlenecks and refine

For analytical workloads where aggregations are common, columnar processing is ideal since it reads only required columns, reducing I/O and speeding up queries. In document-heavy systems like content management, a document database works best for flexible schemas and hierarchical data. For live streaming, real-time systems benefit from distributed frameworks that can handle high-throughput data ingestion with minimal latency. Matching strategies to specific scenarios ensures efficient and scalable pipelines.</p> <button class="contribution__see-more-button absolute bottom-0 right-0 hidden cursor-pointer border-0
