- •Integrated compression (Snappy, Gzip)
- •Full data type preservation
- •Optimized for big data tools (Spark, Hadoop)
Destination - Local File System
FastBCP exports data directly to the local file system, ideal for on-premise processing, testing, or archiving.
Storage Type:
Local Disk
Features:
- •Direct write to local storage
- •No network overhead
- •Flexible path configuration
- •Perfect for development and testing
