Apache ORC

Apache ORC (Optimized Row Columnar) is a file format designed for efficient storage and retrieval of large datasets in big data systems. It organizes data in a column-oriented manner, enabling faster queries and reduced storage space by compressing data effectively. ORC is optimized for big data engines like Hadoop and Spark, making data processing more efficient. Its design allows quick access to specific columns, supports complex data types, and includes features like data compression and statistics for improved query performance. Overall, ORC helps manage massive amounts of data more efficiently and cost-effectively.
