What distinguishes Apache ORC (Optimized Row Columnar) file format from other file formats in big data storage solutions?
- Columnar storage and optimization
- In-memory caching
- NoSQL data model
- Row-based compression techniques
Apache ORC (Optimized Row Columnar) file format stands out in big data storage solutions due to its columnar storage approach, which organizes data by column rather than by row. This enables efficient compression and encoding techniques tailored to columnar data, leading to improved query performance and reduced storage footprint. Unlike row-based formats, ORC allows for selective column reads, enhancing query speed for analytical workloads commonly found in big data environments.
