Microsoft Azure Data Fundamentals DP-900 Practice Question
You are designing an Azure analytics solution that periodically ingests data from a transactional SQL database into a data lake. To reduce network and storage costs, you want to transfer only rows that were inserted or updated since the last load instead of copying the entire tables each time. Which ingestion technique should you use?
Change data capture records insert, update, and delete operations on source tables, allowing an ingestion pipeline to move only the rows that have changed since the previous load. This minimizes the amount of data copied and lowers both network usage and storage costs. Sharding spreads data across multiple databases for scale, but it does not identify changed rows. Data masking obfuscates sensitive fields and is unrelated to incremental loads. A full database backup copies all data every time, which does not meet the requirement to ingest only new or modified rows.
