How to Consolidate Small Files in Hive for Better Performance
In this video, we'll demonstrate a solution to a common Hadoop performance problem: a large number of small files. We'll show you how to combine multiple small CSV files into a single sequential file using Apache Hive, which significantly improves performance. We'll walk you through creating a temporary table, loading your small files, creating a new table with the stored as sequencefile format, and inserting data to trigger the consolidation process.
