dlt Tightens BigQuery Replace and Parquet Writer Control

This week in dlt, a Python data loading framework for ETL and ELT pipelines, the recent activity is mostly about safer destination behavior rather than new connector sprawl. The 13 commits touch BigQuery replace semantics, Parquet writer knobs, Airflow parallel runs, and metric aggregation. For teams running scheduled batch loads, those details matter more than a flashy API.
