Introduction to Data Formats
What are Data Formats?
- Data formats define how data is structured, stored, and exchanged between systems.
- In Big Data, the choice of data format is crucial because it affects:
- Storage efficiency
- Processing speed
- Interoperability
- Compression
Why are Data Formats Important in Big Data?
- Big Data often involves massive volumes of data from diverse sources.
- Choosing the right format ensures:
- Efficient data storage
- Faster querying and processing
- Easier integration with analytics frameworks like Spark, Flink, etc.
Data Formats vs. Traditional Database Storage
| Feature | Traditional RDBMS | Big Data Formats |
|---|---|---|
| Storage | Tables with rows and columns | Files/Streams with structured data |
| Schema | Fixed and enforced | Flexible, sometimes schema-on-read |
| Processing | Transactional, ACID | Batch or stream, high throughput |
| Data Model | Relational | Structured, semi-structured, binary |
| Use Cases | OLTP, Reporting | ETL, Analytics, Machine Learning |
