Small files problem is one of the most common performance killers in Apache Spark and big data systems.
In this video, I explain:
• What is the small files problem in Spark
• Why Spark performs poorly with too many small files
• How small files affect executors, metadata, and job performance
• Real-world impact in production data pipelines
• Common strategies to handle the small files problem
This issue appears frequently in S3, HDFS, and cloud-based data lakes, especially when working with Spark, Hive, and Delta Lake.
If you are a data engineer, big data developer, or preparing for Spark interviews, this is a must-know concept.
