In optimizing a Hadoop cluster, how does the choice of file format (e.g., Parquet, ORC) impact performance?
- Compression Ratio
- Data Serialization
- Replication Factor
- Storage Format
The choice of file format, such as Parquet or ORC, impacts performance through the storage format. These formats optimize storage and retrieval, affecting factors like compression, columnar storage, and efficient data serialization. The right format can significantly enhance query performance in analytics workloads.
