The Register published a report on DuckLake v1.0 and cited our recent post: > In a blog post accompanying the 1.0 launch, Pedro Holanda, DuckDB Labs principal engineer, said the company's benchmark shows 926× faster queries and 105× faster ingestion when compared to Iceberg, the open table format.

Are you streaming into your Lakehouse? Traditional formats suffered with the “many small files” problem — OLAP engines merge them reactively with long jobs. ⏳ DuckLake takes a proactive path: Data Inlining + async flush to parquet while always keeping data queryable ⚡
