ODBC (Open Database Connectivity) allows connection to virtually any database. FastBCP supports ODBC connections for maximum compatibility.
Features:
- •Compatible with any database supporting ODBC
- •Maximum flexibility
- •Standard ODBC driver support
Parallel Method - Ntile
Divides data into N equal partitions based on a numeric column.
Requirement: Requires a numeric distribution column
Available parallel methods with ODBC:
Output Format - BSON (Binary JSON)
BSON is a binary-encoded serialization format, primarily used by MongoDB. FastBCP exports to BSON format for efficient integration with MongoDB ecosystems.
Features:
- •Binary encoding for compact storage
- •MongoDB native format
- •Data type preservation
- •Efficient for document databases
Destination - Google Cloud Storage
Google Cloud Storage provides unified object storage. FastBCP uploads files to GCS buckets with parallel chunked uploads for fast transfers.
Storage Type:
Cloud Object Storage
Features:
- •Parallel chunked upload
- •Service account authentication
- •Bucket and prefix configuration
- •Multi-regional storage classes
