File Formats

Hive supports several file formats, each with its own advantages:

1. TextFile: The default format. It's simple and human-readable but not the most efficient for large datasets.

2. SequenceFile: A binary format that provides better performance than TextFile. It's suitable for large datasets and supports compression.

3. RCFile (Record Columnar File): Optimized for read-heavy operations. It stores data in a columnar format, which can improve query performance.

4. Avro: A row-based storage format that supports schema evolution. It's great for data serialization and deserialization.

5. ORC (Optimized Row Columnar): Highly efficient for both read and write operations. It provides excellent compression and supports complex data types.

6. Parquet: Another columnar storage format that offers efficient data compression and encoding schemes. It's widely used in big data processing.

Each format has its strengths, so the choice depends on your specific use case and performance requirements.

By every year Hive is getting outdated I think so.
