File-based batch processing
In addition to real-time API calls, DQE supports bulk data quality processing via SFTP. You submit a CSV file and DQE processes each record, returning enriched output columns. This is suited for periodic data cleansing, migration projects, or large-scale enrichment campaigns.
See File-based batch processing for details.
Matching and deduplication
DQE Matching compares, identifies, and reconciles records based on configured matching rules, supporting deduplication use cases across large datasets.
