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 - JSON (JavaScript Object Notation)
JSON is the most widely used data exchange format on the web. FastBCP exports data to JSON Lines (NDJSON) format, with one record per line for efficient streaming.
Features:
- •JSON Lines (NDJSON) format
- •One record per line for streaming
- •UTF-8 encoding
- •Compatible with all JSON parsers
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
