ORC file format

ORC (Optimized Row Columnar) is a file format designed for storing large amounts of data efficiently. It organizes data by columns rather than rows, which improves compression and speeds up querying. ORC files are optimized for big data systems, allowing quick data retrieval, reduced storage space, and efficient processing. They are commonly used in data warehouses and analytics platforms to handle complex, large datasets with high performance and cost-effectiveness.
